I suggest clicking the "Dr Sorotzkin" link in my signature. He has some good stuff on perfectionism. Both reading material and recorded lectures. Perfectionism is a BIG cause of stress, which leads to acting out of course.
Or you can follow dov's advice and get off your truck and get on to a trycycle.
Same idea. You are not perfect. Get over it.
I once made up this quote that some people liked.
Here's the quote:
"I try to portray a 'perfect' image, but I am so much happier when I can accept my 'imperfect' reality."
