@Xxjuggernaut You must know how to challenge yourself and when it gets tough find new workarounds but if you can complete the challenge you gave yourself then you'll find yourself coming out of it a better person.
Calling this a fault in their judgement is very discouraging to people. Its in your rights to criticize it but maybe try to be bit nicer? Unless you feel your whole experience and time has been wasted reading this story.
Telling a fat person who went on a diet but broke it "what's the point of going on a diet if you're gonna break it anyway?" is something people commonly do. And it does effect them in that they get discouraged from trying to do that diet again. But if you tell them that they did great, that next time they'll get farther then they have the motivation to try again...but well, you'll get nothing out of it either way, so I guess you're right, huh? Don't mind what I said then, keep on.
