I have a friend from undergrad who would only go to bed after everyone else on the floor was asleep because she didn't want to miss anything. I think perfectionism is tied to that feeling of not wanting to miss something. What if you used the wrong dish soap for years! Not realizing that there is a much better, cheaper dish soap available from an artisan soap-maker in Wyoming! I am not being sarcastic (maybe a little - but I do it too)!
