"There are certain things in life where you know it's a mistake but you don't really know it's a mistake because the only way to really know it is a mistake is to make that mistake and look back and say, Yup, that was a mistake. So really, the bigger mistake would be to not make the mistake because then you'll go your whole life not really knowing if something is a mistake or not."
-- Ted Mosby, How I Met Your Mother
