None of my children are perfectionist - probably the opposite. However, I have found team competitions like Destination Imagination to be very helpful in injecting some reality. They clearly cannot be perfect because they cannot control their team mates. It was also helpful for DS to realize that he cannot lead by pushing everybody to do things exactly the way that he wanted. Instead, he has to account for other people's strengths and weaknesses and sometimes compromise to get the best results for the team.
