Inherent in being proactive and trying things and not waiting to be told what to do is the fact that you're going to fail, you're going to make mistakes, and you're probably going to piss people off. And if you're not pissing people off, if you don't have haters, if you're not putting yourself in a situation that has some risks associated with it, you're probably not going to realize your full potential.
Happiness comes from within. It is not dependent on external things or on other people. You become vulnerable and can be easily hurt when your feelings of security and happiness depend on the behavior and actions of other people. Never give your power to anyone else.
