If you want the rainbow, you gotta put up with the rain. The world is moved not only by the mighty shoves of the heroes, but also by the aggregate of the tiny pushes of each honest worker. 1 is, don't sweat the small stuff. If you want to be listened to, you should put time in listening. No one can make you feel inferior without your consent.
