the terrible thing is, when you never learnt from it, no?

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.
