Two recent articles about public speaking by those with dyslexia

 

  

 

 

 

 

 

 

 

The Wikipedia article about Dyslexia says it is:

 

“…also known as word blindness, is a learning disability that affects either reading, writing, or speaking. Different people are affected to different degrees. Problems may include difficulties in spelling words, reading quickly, writing words, ‘sounding out’ words in the head, pronouncing words when reading aloud and understanding what one reads.”

 

There is an article by Jarone Macklin-Page at ProDyslexic on June 10, 2025 titled Public Speaking Tips for Dyslexic Individuals with the following headings:

 

Start With Why Structure Like a Pro

Don’t Memorise, Map It Out

Practice Out Loud, Then Practice Being Still

Stand in the Space Before You Speak

Use Visual Anchors to Support You

Channel Your Emotions, Don’t Suppress Them

Still Feel Daunted? You’re in Good Company

You Don’t Have to Be Perfect to Be Powerful

 

Another article at AmberWillo on July 24, 2026 titled Dyslexia and Public Speaking: Challenges and Effective Strategies has these headings:

 

Common Public speaking Challenges

  Word Finding and Fluency Difficulties

  Reading Aloud and Processing Speed

  Memory and Organization Issues

  Anxiety and Confidence Barriers

 

Practical Tips

  Preparing and Structuring Your Speech Effectively

  Using Visual Aids and Mind Maps

  Practicing Techniques for Fluency and Confidence

  Managing Anxiety and Building Self-Confidence

An xkcd cartoon shows a hilariously overloaded flag design

 

 

 

 

 

 

 

 

 

 

 

 

 

Randall Munroe’s xkcd comic for May 25, 2026 (which I colorized to yellow) has an awful flag design. Apparently all dozen ideas from the flag design committee were included. The worst is the bottom fringes that remind me of a for sale notice thumbtacked to an office bulletin board. The flag is analyzed at Explain xkcd. 

 

On May 14, 2016 I blogged about how Looking at flag design will change how you make PowerPoint slides. And on September 23, 2017 I posted about an example - A new, simpler, better flag for the city of Pocatello, Idaho. On June 30, 2020 I blogged about how Mississippi is going to change its state flag.

 

 

Clip art of meshed or locked gears

 

 

 

 

 

 

 

 

 

 

On November 17, 2020 I blogged about Smoothly meshing gears or jammed gears. Meshed gears describe graphically how individuals or parts of an organization can work together smoothly (as is shown above via an image modified from OpenClipArt).

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Jammed gears describe the opposite. At OpenClipArt there is a set of three gears locked together, shown above.

 

There is a long article by Bartoz Ciechanowski on February 12, 2020 titled Gears with discussions, animations, multiple gears, and three jammed ones at the very end.

 

 

Does the design of slides for medical lectures follow the Cognitive Theory of Multimedia Learning?

 

 

 

 

 

 

 

 

Of course not! There is a very recent and serious article by Rajin Le Blanc and Nicola Cooper at Clinical Teaching on December 10, 2025 which is titled Investigating Death by PowerPoint: Do Medical Lecturers Adhere to the Cognitive Theory of Multimedia Learning in Their Slide Design? They examined 52 lectures presented at the University of Nottingham. And they found that:

 

“Students were exposed to text‐heavy slides 84.4% of the time, an approach that CTML [Cognitive Theory of Multimedia Learning] shows impairs learning through violating the minimal text principle. In addition, the mean word count per slide was 38.2 – significantly more than the ‘few words’ suggested by the principle. Lecturers did however use images relatively frequently at 59.9% of the time.”

 

Counting its title, my slide example modified from Section 2.1 (and shown above) has 85 words, more than twice the 38.2 average.

 

There is another succinct four-page pdf article by Jacob B. Waxman and Sue J. Goldie from the Center for Health Decision Science at the Harvard T. H. Chan School of Public Health titled Cognitive Theory of Multimedia Learning. That theory is also described by Richard E. Mayer in the 2020 third edition of his book, Multimedia Learning.

 

Displaying risks from vaccines and other dangers

 

 

 

 

 

 

 

 

 

 

 

 

There is an interesting article from Edzard Ernst on July 16, 2025 titled Yes, vaccination risks are real – but how do they compare with other dangers? In order to show the range from the tiny one in a hundred million for the MMR vaccine to one in 1,100 for drowning (and up to one) we need to use a chart with a logarithmic scale - as is shown above. I had discussed risk in a post on November 12, 2024 titled I am not going to throw out my black plastic spatulas.

 

Also, back on January 13, 2010 I had blogged about How thin is “extremely thin”? and used a table with a powers of ten for comparing thicknesses over a range in centimeters from one to one in ten to the minus eighth power.

 

8 presentation mistakes: how to avoid them and fix them

 

 

 

 

 

 

 

 

 

 

 

  

 

 

 

 

 

 

There is a useful post by Naba Ahmed at the Prezi Blog on October 15, 2025 mistitled 8 presentation mistake: how to avoid them and fix them. Those mistakes are:

 

1]  Don’t read directly from your slides.

2]  Avoid overwhelming slides with text.

3]  Create a clear visual flow.

4]  Give your presentation a solid structure.

5]  Pace your speaking.

6]  Use confident body language.

7]  Learn to read audience cues.

8]  Don’t underprepare.

 

Regarding her first point, back on June 10, 2015 I blogged about Don’t annoy us by reading your PowerPoint slides.

 

The article also has advice on How to design slides that connect:

 

Guide the eye with visual hierarchy.

Use color and contrast with purpose.

Choose your fonts wisely.

Select powerful, relevant images.

Balance your visuals and text.

 

I blogged about balancing visuals and text in a post on February 19, 2014 titled Assertion-Evidence PowerPoint slides are a visual alternative to bullet point lists.

 

And the article has sections on how to Master Audience Engagement and to Perfect Your Delivery.

 

A star with eight points was adapted from one at OpenClipArt.

 

Aphantasia means not having a mind’s eye

 

 

 

 

 

 

 

 

 

 

 

 

 

Via interlibrary loan from the Twin Falls Public Library I got and have been reading a 2025 book by Adam Zeman titled The Shape of Things Unseen: A new science of imagination. There is a Google Books preview to page 43 of it. On pages 13 and 14 he says:

 

“But Keat’s acute sensibility is deeply puzzling to the 2 – 3 percent of us who turn out to lack imagery entirely. The existence of people whose ‘powers’ of visualisation ‘are zero’ was noted by the remarkable Victorian psychologist Sir Edward Galton in the 1880s. But neither Galton himself nor his followers pursued this intriguing lead. In 2015, with colleagues in Edinburgh, I described 21 people who had always lacked a mind’s eye [Adam Zeman, Michela Dewar, and Sergio Della Salla, Cortex, 2105, Volume 73, pages 378 to 380: Lives without imagery – congenital aphantasia], coining the term ‘aphantasia’ to denote this variation in human experience: we had borrowed Aristotle’s term for the capacity to visualize, phantasia, adding an ‘a’ to indicate absence. The public interest that followed came as a huge surprise: after five minutes on breakfast TV discussing the work, I watched emails dropping into my inbox many times every second. One of the most memorable came from a Silicon Valley entrepreneur, Blake Ross, the co-creator of Mozilla Firefox, who wrote a feisty Facebook post about his realisation that he was aphatasiac: ‘If I tell you to imagine a beach, you can picture the golden sand and turquoise waves. If I ask for a red triangle, your mind gets to drawing. And mom’s face? Of course. You experience this differently, sure. Some of you see a photorealistic beach, others only a shadowy cartoon, Some of you can make it up, others only ‘see’ a beach they’ve visited. Some of you have to work harder to paint the canvas. Some of you can’t hang onto the canvas for long. But nearly all of you have a canvas. I don’t. I have never visualiszed anything in my entire life. I can’t ‘see’ my father’s face or a bouncing blue ball, my childhood bedroom or the run I went on ten minutes ago. I thought ‘counting sheep’ was a metaphor. I’m 30 years old and I never knew a human could do any of this. And it is blowing my goddamned mind.’

 

Many others wrote along similar lines – one contact wrote of ‘the amazing click of realization we all get when we first heard about it.’ There turned out to be a substantial community of aphantasic folk who had long been trying to articulate this quirk in their psychological nature and were glad of a term with which to describe it.

 

We shall return to the recent discovery of aphantasia. For now, the existence of folk who get by perfectly well without a mind’s eye – indeed in some cases, like Blake Ross’s, without any conscious sensory imagery at all – underlines the huge variability of our imaginative experience and inner lives. This helps to explain my teenage puzzlement at a lively but hazy recollection of the gallery: I have average imagery vividness, but it extends across the sensory spectrum – I can see in my mind’s eye, hear in my mind’s ear, walk with my mind’s legs with reasonable ease. When I recalled the gallery, I precisely imagined being there – the feel of the boards beneath my feet, the still gallery air, the scent of canvas, a certain mood, as well as the look of the paintings. The ability to re-experience events in this richly integrated way – much as we experienced them in the first place – is a key source of our sense that our recollected or imagined memories are ‘true’, even when the fine details prove to be elusive.”

 

There also is a magazine article by Larrissa MacFarquhar in The New Yorker for October 27, 2025 titled Some People Can’t See Mental Images. The Consequences Are Profound. And there is another 20-page pdf article with 165 references by Feiyang Jin, Shen-Mou Hsu, and Yu Li in Vision on September 22, 2024 titled A Systematic Review of Aphantasia: Concept, Measurement, Neural Basis, and Theory Development.

 

 

 

 

 

 

  

Yet another article by David J. Wright et al. at Frontiers in Psychology on October 15, 2024 is titled An international estimate of the prevalence of differing visual imagery abilities. They surveyed 3049 people with the results shown above on a bar chart. Just 1.2% had aphantasia. Another 3% had low imagery -  hypophantasia. 89.9% had normal visual imagery, and the other 5.9% had high imagery – hyperphantasia.

 

 

 

 

 

 

 

A second bar chart shows similar results just for 887 Canadians in that larger sample. Just 1.7% had aphantasia. 3.6% had low imagery -  hypophantasia. 89.1% had normal visual imagery, and the other 5.6% had high imagery – hyperphantasia.

 

Still another article by Rish P. Hinwar and Anthony J. Lambert at Frontiers in Psychology on October 14, 2021 is titled Anauralia: The Silent Mind and Its Association With Aphantasia.

 

The cartoon was assembled using images for an eye and mind from OpenClipArt.

 

 

Give people a picture to teach them about health

 

 

 

 

 

 

 

 

 

 

 

There is a brief and useful article by Pernilla Garmy in the Journal of Research in Nursing on October 23, 2025 titled Reaching beyond words: supporting self-care through visual health education. She says that:

 

“From my own experience as a nurse and educator, I know that there is no single educational format that works for all patients. Some people benefit from verbal dialogue, others prefer detailed written materials. But for many, visual aids are a crucial complement. Pictures can clarify, engage and motivate – especially when literacy is limited or when energy and focus are low due to illness, stress, or comorbidities.

The fact that this resource is printed – not digital – also matters. A physical object can be held, browsed at one’s own pace, and brought along to consultations. It does not require a smartphone, internet access, or digital skills; which may be barriers for some groups. At the same time, digital tools may be more effective in other contexts. The point is: healthcare professionals need a flexible set of educational tools, adapted to the needs, abilities, and preferences of each individual.”

 My PowerPoint cartoon was assembled from those of a nurse and a pain scale at OpenClipArt.  

 

 

Use ugly sketches to give a great presentation

 

 

 

 

 

 

 

 

 

 

 

There is an interesting 11-minute TEDx talk by Martin J. Eppler recorded on May 18, 2024 at TEDxDonauinsel and posted on December 31, 2024 titled Want to Give a Great Presentation? Use Ugly Sketches | Martin J. Eppler | TED. He said to:

 

Use provisional, unpolished images

Apply fitting visual metaphors [simple and concrete]

Vary your visuals

 

At 7:20 he has a monochrome cartoon image with visual metaphors (and captions at the right). My color PowerPoint version (with captions at the left) is shown above.

 

Martin also has a 32-page e-book from 2022 titled An Introduction to Visual Variation for Better Leading, Learning, and Living.

 

My PowerPoint slide used cartoon images of a bridge and car from OpenClipArt.  

 

Boil your strategy down to just one clear visualization

 

 

 

 

 

 

 

 

 

 

 

 

 

In the July-August 2025 issue of the Harvard Business Review, on pages 98 to 107, I found a useful ten-page article by Joao Cotter Salvado and Freek Vermeulen titled You Should Be Able to Boil Your Strategy Down to a Single Clear Visualization. It is referenced here, and an excellent graphic from it is shown here. The description for that graphic says that:

 

“Our research into the best way to communicate strategies reveals five key design principles, which can be seen in this visualization about the bank Capitec. It clearly illustrates the bank’s plan to build a network of accessible, user-friendly branches to deliver a value proposition of banking services that are simple, unintimidating, and affordable for low-income customers opening their first bank accounts.

 

1]  Group your ideas into three or four main concepts that form the base of your model.

 

2]  Within those concepts, add layers of detail that describe their concrete implications and how to implement the strategy.

 

3]  Use color and shading, but judiciously – only to distinguish layers.

 

4]  Indicate clear relationships among the elements – for instance, with connecting lines and arrows that delineate flows.  

 

5]  Make your framework easier for viewers to process by organizing it horizontally.

 

To read the full article you can look at the Business Source Premier database in EBSCOhost over at your friendly local public library. But you can also find a slightly different version in another article with the same title from June 24, 2025 by Joao Cotter Salvado.

 

Using histograms for visualizing statistics from playing a hundred games of solitaire

 

 

 

 

 

 

 

 

 

 

 

 

 

It often is helpful to show the details of data rather than just a mean and standard deviation. Recently I played a hundred games of Solitaire to generate the game times shown above via a histogram (created using Excel with bins ten seconds wide). The mean time to complete a game is 221 seconds (3 minutes and 41 seconds), and the standard deviation is 31 seconds. But the range goes from 160 to 335 seconds. The distribution is roughly symmetrical, with three longer outliers.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

I also kept track of the number of moves per game, as shown above via another histogram using a bin width of five. The mean is 133 moves, and the standard deviation is 13 moves. The range goes from 116 to 170 moves. The distribution is skewed positively (to the right) with two outliers.

 

Cracker Barrel made their new logo too abstract and then they dropped it

 

 

 

 

 

 

 

 

 

 

 

The old logo for the Cracker Barrel restaurant chain has founder Dave Evin’s Uncle Herschel nostalgically sitting in a wooden chair next to a barrel, as is shown above on the wall of their Boise location.

 

A press release on August 19, 2025 at PR Newswire titled Cracker Barrel Teams up with Country Music Star Jordan Davis to Invite Guests to Discover “All the More” this Fall described the abstract new logo:

 

“Its more popular menu offerings like farm fresh scrambled eggs and buttermilk biscuits even serve as inspiration behind the hues of a refreshed color palette featured in the new campaign. Anchored in Cracker Barrel's signature gold and brown tones, the updated visuals will appear across menus and marketing collateral, including the fifth evolution of the brand's logo, which is now rooted even more closely to the iconic barrel shape and word mark that started it all.”

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

That new logo with the sideways barrel and minus hoops (shown above) was so abstract that the Wikimedia Commons web page said:

 

“This logo image consists only of simple geometric shapes or text. It does not meet the threshold of originality needed for copyright protection, and is therefore in the public domain.”

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

I squeezed it, squared off the bottom and top, and added a pair of hoops to produce the more recognizable version shown above.

 

The new logo got a lot of negative feedback, and it quickly was dumped. For example, an article by Lorraine Taylor at Fox News on August 22, 2025 is titled Cracker Barrel faces customer criticism after ditching iconic 48-year-old logo for new design. A second article by Ali Abbas Ahmadi at BBC News on August 26, 2025 is titled US restaurant chain Cracker Barrel scraps new logo after backlash. A third article by Megan Cerullo at CBS News Moneywatch on August 27, 2025 is titled Cracker Barrel refreshed its logo and paid the price. Here’s what brand experts say went wrong. Experts said they went generic and severed the logo from its roots. A fourth article by Sarah Fortinsky at The Hill on August 27, 2025 is titled White House claims credit after Cracker Barrel reverts logo.

 

 

Two very useful articles in the August 2025 issue of Toastmaster magazine on Five Tips for Depicting Data and Making Your Data Presentations Come to Life

 

 

 

 

 

 

 

 

 

The August 2025 issue of Toastmaster magazine has two very useful articles. One by Florian Bay on pages 20 to 23 is titled 5 Tips for Depicting Data and subtitled How to use numbers and graphs to create a compelling story. His five headings are:

 

Be Clear on Your Purpose

Select the Right Visual

Remove the Clutter

Engage with Colors but Don’t Create Rainbows

Use Text to Guide Your Viewers

 

The first two line and column bar charts, at the bottom of Page 20 are missing a label for the vertical axis, which should be Number of UNESCO Sites. As shown above, I have added it in red.

 

Regarding pie charts, he says:

 

“Visualizing proportions? Then use a pie chart, but only if you’ve got two or three slices to share; any more than that and the proportions get hard to interpret. Stacked bar charts can also be useful.”

 

I don’t think pie charts ever are useful, as I discussed in a blog post on September 16, 2008 titled Pie charts do not speak clearly; they just mumble and one on July 29, 2022 titled Is there any excuse for using a pie chart?

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

And his example with Yearly Passengers in London Heathrow Airport 2005-2024 (shown above) has the numbers of years shown vertically rather than horizontally. My Excel version omits the bullseyes around the pandemic data and just shows numbers for all those data points. (On July 4, 2017 I blogged about Why is your audience tilting their heads sideways?)

 

The second article by Charlene Phua following on pages 24 and 25 is titled Make Your Data Presentations Come to Life and subtitled Avoid these 4 missteps to ensure your audience stays engaged. Her four headings are:

 

Including data that isn’t relevant to topic or audience

Having an inaccurate gauge of your audience’s understanding

Providing data with no context or comparison

Neglecting other aspects of your performance

 

 

 

 

 

 

 

 

 

 

 

 

 

 

For the third she uses the example of annual global carbon dioxide emissions. She didn’t mention a number, but in 2022 they are 38,521,997,860 tons. We can ask What’s in it for me? The global Population is  8,021,407,192 people so it is 4.802 tons per capita, or 9605 pounds. Per day it is 26.3 pounds, and converting that to a cube of dry ice, it is one 7.75 inches on a side, as shown above.

 

On December 23, 2024 I blogged about How should we present a huge number like the two billion dollars earned by the Taylor Swift Eras tour? And on July 12, 2016 I blogged about How to make statistics understandable. Also, on August 17, 2011 I posted on How to make a large number incomprehensible or comprehensible and on July 15, 2011 I blogged on What can we say about a really big hole in the ground?

 

 

A visit from the mythical Bar Chart Police could have improved the 2025 book Speak, Memorably: the art of captivating an audience

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

I have been reading a 2025 book by Bill McGowan and Juliana Silva which is titled Speak, Memorably: the art of captivating an audience. It’s not awful, but it’s not great either. There is no index. On August 2, 2025 I posted about A bogus car story from the 2025 book Speak, Memorably.

 

On page 10 of that book they state that:

 

“….in the chapters that follow, we commissioned a survey by the Clarity Media Group of over one hundred people. The respondent pool was comprised of full and part-time employees between the ages of twenty-five and sixty-five.”

 

There are 31 horizontal bar charts shown in this book on pages 11, 15,21, 27, 36, 38, 55, 58,60, 71, 113, 114, 135, 139, 153, 155, 168, 183, two on 185, 194, 197, 199, 204, 214, 215, 226, 228, 229, 243, and 244. They are shown in monochrome, and only are 3.3” wide by 1.5” high. The percent is labeled at the center of the bar, and the description of the question is to the right of the bar.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

My slightly different Excel version of the chart on page 11 for Do You Consider Your Public Speaking Skills at Work Important? is shown above. But those bars are not presented in what should be their order, with the most significant and largest percentage placed at the top. My revised version also is shown above.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Another example from page 168 about How Do You Determine What Your Audience Wants to Know? and a corrected version are shown above.

 

18 of 31 charts have this incorrect order, those on pages 11, 21, 27, 36, 113, 139, 153, 155, 168, 183, 185 bottom, 194, 199, 204, 214, 215, 228, and 229.

 

 

 

 

 

 

 

 

 

 

 

 

And as shown above, the chart on page 21 for How Often Do You Know with Certainty the First and Last Sentence of Each Slide? has silly labels from top to bottom of: Never, Rarely, Sometimes, and Frequently. That is opposite to what should be: Frequently, Sometimes Rarely, Never. They used the same sequence on pages 27, 113, 139, 155, 199, and 215. Also the chart on page 194 has Never, Seldom, Occasionally, Frequently.

 

Back on September 6, 2022 I blogged that we should Beware of surveys with small sample sizes, which have large margins of error. There is a Wikipedia page about Margin of error. For a typical national survey with a sample size of 1,000 the margin of error is 3.1%. For a sample size of 100 the margin of error instead  is 9.8% (as is shown above in my revised version for page 11).

 

Is the difference between the largest percentage and the second largest percentage twice the margin of error (or 20%)? That only is true for ten charts, those on pages 36, 55, 58, 71, 135, 139, 168, 183, 185 top, and 215. Not the other 21 charts!

 

I first mentioned the mythical Bar Chart Police (and showed a version of their badge) in a post on November 3, 2023 titled Five of six British age groups are more confident about public speaking after COVID.

 

Can you spot a fake photograph?

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

There is a twelve and a half minute TED Talk by Hany Farid that was given in Vancouver on April 10, 2025 and posted at YouTube on July 18, 2025. It is titled How to Spot Fake AI Photos | Hany Farid | TED. He discusses using vanishing points and shadows:

 

“If you image parallel lines in the physical world they will converge to a single point, what’s called the vanishing point.”

 

“Surprisingly shadows have a lot in common with vanishing points. Here what I’ve done is I’ve annotated a point on the shadow with the corresponding part on the bottom of the rail that is casting that shadow, and I’ve extended those lines outward. And they intersect, not at a vanishing point, but at the light that is casting that shadow.”    

 

There also is a ten-page article by Hany Farid at PNAS Nexus on July 29, 2025 titled Mitigating the harms of manipulated media: Confronting deepfakes and digital deception. Reference #35 from that article is a 13-page pdf preprint titled Perspective (In)Consistency of Paint by Text which discusses vanishing points, shadows, and reflections.

 

A multiple-exposure spirit photograph from 1901 by S. W. Fallis with a portrait of John K. Hallowell and super-imposed faces of fifteen deceased people including George Washington and Queen Victoria came from Wikimedia Commons.

 

 

A humorous YouTube video from Don McMillan about Venn Diagrams

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Back on December 10, 2013 I blogged about Communicating ideas using Venn diagrams and other simple graphics. In another blog post on February 28, 2015 titled Don’t make things any more complicated than necessary I discussed Simon Sinek’s use of a bullseye (concentric circles) Venn diagram.

 

There is a humorous five-minute YouTube video by Don McMillan Comedy on July 8, 2025 titled Venn Diagrams About Venn Diagrams.

 

At 0:30 he explains that diagrams are overlapping circles with different colors (as shown above).

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

At 2:05 he explains that a comedian has to be funny, socially challenged, and not afraid of public speaking (as shown above).

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

At 2:50 he explains that a motivational speaker has to be funny, not socially challenged, and not afraid of public speaking (as shown above). Unlike a comedian you will tell people how they should live their lives.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

At 3:00 he explains that a mime has to be funny, socially challenged, and afraid of public speaking (as shown above).

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

At 3:10 he explains that Elon Musk is not funny, socially challenged, and not afraid of public speaking (as shown above).

 

 

 

 

 

 

 

 

 

 

 

 

 

 

He has another seven-minute YouTube video titled The Career Venn Diagram – Comedy in Place (E61) which at 1:25 has six circle diagram (as shown above) with Math Skills, Problem Solving, People Skills, Drinking, Heartless, and OCD.
