I suffer from perfectionism as well. However, I'm sill trying to work this out and don't have any solutions. One aspect, though, that I learned is that the cognitive distortion of black-or-white thinking is predominant. So, the thing is that if one can't do it right the first time then one doesn't do it at all. There is also catastrophic thinking as well. My therapist gave me a magazine article from 1980 that described a lot of it. I get overwhelmed by anything that even looks complicated, and it's holding me back from doing certain hobbies.
