Judgements pushes us to do things we aren't supposed to do.
It's okay to feel weak at times, but that doesn't mean you can't deal with reality. You might think you are below average, but it's not a big issue.
The biggest problem here is that we don't accept who we are. Accepting flaws and weakness, doesn't make us coward, but it makes us human.
You are Not Perfect, but You are Normal and You don't have to prove anything to anyone.
Just prove yourself, that you're normal by doing what is right, rather than regretting a bad decision.
