Failing is very important ! It makes you grow as a person and builds up you’re character makes you a stronger person as well if failing didn’t exist winning wouldn’t either failing teachers you what ever you want it to teach you if you decide to fail and give up that just shows what of a weak person you are but if you decide to continue it teachers you that you are a go getter no matter what failings is important it helps you grow in so many ways you decide !
