If you do a Google search for perfectionism and creativity, you’ll notice that there are an awful lot of articles out there suggesting that perfectionism “kills” creativity (who knew perfectionism was so homicidal…).
I think we probably all know on some level that pursuing excellence is better (at least healthier) than pursuing perfection. But you might be hard pressed to convince a perfectionist that excellence is good enough. At least, I certainly remember a time in my life when excellence felt like settling, and perfect was the only acceptable standard to aim for.
