"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’s a mistake is to make the mistake and look back and say, ‘Yep, that was a mistake.’ So, really, the bigger mistake would be to not make the mistake, because then you’d go your whole life not really knowing if something is a mistake or not."
