"In recent years, psychologists have studied the relationship between persistence and creative achievement. They've discovered that the ability to stick with it-- the technical name for this trait is grit--is one of the most important predictors of success."
"What grit allows you to do is take advantage of your potential," [Angela] Duckworth [a psychologist at the University of Pennsylvania] says. "Because even the smartest, most talented people still need to practice.
"A down-and-out nation saw this horse and rider as a symbol of what could be accomplished though grit and spirit."
Then I ran across What Attributes Really Matter for Creative Success. This post really pulls together both these books/authors along with several others who have written about grit.
...author James Clear argues that grit is the number one defining element of geniuses:
“How do creative geniuses come up with great ideas? They work and edit and rewrite and retry and pull out their genius through sheer force of will and perseverance. They earn the chance to be lucky because they keep showing up…No single act will uncover more creative powers than forcing yourself to create consistently…”
Grit... possibly my new favorite word.
