In 2018 only you can prevent bad presentations

Once again at the New Year it is time to resolve to make good rather than bad presentations. You can prevent producing a bad presentation by doing a better job of planning to tell a coherent story, illustrating with useful graphics, and rehearsing sufficiently.

This is the fourth in my series of illustrations continuing those from 2015, 2016, and 2017. The finger pointing at you came from Wikimedia Commons. The image of Theodore Roosevelt from around 1913 was adapted from one at the Library of Congress. The finger pointing lady and pointing hat man are from Openclipart.
