In her forthcoming book, Angela Duckworth, one of our favorite experts on grit, has some interesting advice about quitting. For example, she suggests that high schoolers should be encouraged to stick with a new endeavor for at least a year before throwing in the towel. In other words, grit doesn’t mean never you never quit. It just means you don’t quit easily: It’s a matter of why and when. After all, trying new things can be as important as seeing old ones through, and sometimes you’ve got to quit one project to take on one that better suits you.
