Perfectionism is not a fix for this. Indeed, perfectionism can be a cause, by diverting energy and attention away from critical things toward polishing the spot on the wall in the basement while the load bearing walls and electrical wiring remains unaddressed. I would argue that perfectionism is also about an inability to prioritize, something which, in the real word with all its time limits, will bite you.
