This has been a struggle area for me too. I think to myself, "if I can't do it right,why bother doing it at all." As a result, I don't do things that would help me move ahead in my healing and breaking through some barriers. This state of mind with perfectionism can cause a lot of unnecessary pain. When I keep it in perspective that everyone makes mistakes and when I see how others don't seem affected when they make mistakes, it helps me relax. I try not to beat myself down when I goof, but try to fix it and apologize. More times than not, those around me forgive me and this has helped me be more forgiving of myself.
