Think and keep quiet among those you don't trust.

Its a sign of weakness to lament about things which you entirely have no control over.

Stop thinking that nobody is “good enough”.

TRUST is like a paper once it’s crumpled it can’t be PERFECT again.

It takes time to earn trust and it takes time to learn to be open enough to work in at team in an effective way so that every contribution is "valuable" regardless of your personal opinion.
