I just wanted to emphasize to not focus on rewards so much. Failure makes you more resilient.
This resilience can be a reward in itself.
Just because someone doesn't understand your post and downvotes it is no reason to have to explain. Some people have less than a cup half empty, they have it turned upside down. +1 to you.
He is trying to tell him not to give up. That you can fail your way to success. Can't you see that?
