worth

What does it mean to be worth something? What does it even mean to be worth?
I think no one should have the audacity to ever tell any one that they are not worthy or worth of something, anything. Because if you are not 'perfect' then you should not have mind to tell someone anything, and if you thing that you are 'perfect' instead of telling people their flaw and bringing they down, you should help them reach their full potential.
