To know oneself, one should assert oneself.
The most effective way to do it, is to do it.
If you've got a talent, protect it.
Expect problems and eat them for breakfast.
Things do not happen. Things are made to happen.
Problems are not stop signs, they are guidelines.
Be gentle to all and stern with yourself.
Never complain and never explain.
Who seeks shall find.
I can, therefore I am.
That song is a story that shows how easily you could get slipped into being labeled as the bad guy, even though what you really trying to do is tell the bad guy to leave you alone.
