Perfectionists are an extreme example of this destructive tendency. It’s hard to argue with the perfectionist’s intentions. He has high standards. He works hard. He wants to do everything well—so well that it’s perfect. And, of course, he falls short. There’s a fine line between trying diligently and being a perfectionist. But it’s important to understand the difference between diligence and perfectionism and to stay on the diligent side of the line.
