Angela Duckworth introduced the world to the concept of grit—of being dogged and determined in pursuing an idea in a particular direction.2 Grit can be a really important quality, but it necessitates a narrow perspective, a zeroing in on the one thing that can bring about success. Athletes who achieve world-class success have all had to have grit, focusing on one activity and letting others go, and Duckworth herself talks about the need to be selective and not broad. This can work for some people, but is not the best approach for everyone.
