Haha, I worked with a guy that had seriously bad OCD. He had many a sign/note/reminder all over the place to not let the perfect become the enemy of the good. :D
I've had to remember than in school all the time. Same with some of the smaller projects on the car. I have to know when to stop trying to make things better.
Wish wives would learn that too... Us husbands are already so perfect we can't get any better lol
