Novelist John Irving says there's something positive in knowing what your limitations are.
He learned that both as a wrestler and a writer.
"It was kind of a blow to me to discover early on in my wrestling career that despite my technical superiority and my excellent condition, somebody who was not my equal in those capacities but just was a marvelous athlete would get the better of me in certain situations," Irving said.
Irving, who wrote "The World According to Garp" and the screenplay for his novel "The Cider House Rules," also said he learned early on that his dyslexia made him make more mistakes than other students and that every assignment would take him twice the time it took them.
But in the long run it helped him as a writer because he accepted that "everything you do you have to do again, and your capacity for rewriting is the only thing that separates you from people who do things in a hurry."
