People who consider themselves perfectionists don't nearly realize how crippling it really is

Doing a lot of things to be productive is common, wanting to do things effectively and high quality is common. Those aren't true perfectionism. True perfectionism is your mind eating itself, it's never being satisfied, always trying to do better, ending up worse due to paralysis. It's procrastination paradoxically. It's what appears to be laziness to the outsider gaze.
