On July 17, 2018 at his Manner of Speaking blog John Zimmer posted about Quotes for Public Speakers (No. 288) – Salvadore Dali:
“Have no fear of perfection. You’ll never reach it.”
That quote also appeared in a May 11, 2018 article by Jennifer M. Wood at Mental Floss titled 25 Outrageous Quotes from Salvador Dali – where it was #4 and punctuated with a dash rather than a period between the clauses. Another version with a semicolon has been attributed to Marie Curie.
I was surprised that John hadn’t also referred to his February 13, 2011 blog post that Perfect Public Speaking is an Asymptote, which had inspired my February 20, 2011 blog post on Effort and an asymptote and the graphic shown above.
