Perfectionism kills creativity. It drives the brain to the left side of the road in hopes of removing all imperfections—an editing process. Without feeling the freedom to make mistakes, a person cannot create. But the idea doesn’t stop there, else all perfectionists would be doomed from ever creating (and from the liberation of learning to do so).
Perfectionism, if it’s anything like what I consider my own perfectionism, is a flight from or fight against fear. In this case, it battles the fear of failing to meet some standard.
