Healthy striving is about striving for internal goals, and wanting to be our best selves. Perfectionism is not motivated internally. Perfectionism is about what people will think. And you do not see effective leaders in corporations sitting on an email for three hours to make sure it's worded just perfectly. You don't. They have work to get done.. You don't see elite athletes letting themselves be discouraged by a bad workout or a single bad performance. It happens all the time. They're accustomed to winning, they're accustomed to losing. Once perfectionism becomes the goal, they're out of the sport.
