Expect problems and eat them for breakfast.
Go for it now. The future is promised to no one.
To be a good loser is to learn how to win.
Be thine own palace, or the world's thy jail.
To know oneself, one should assert oneself.
By failing to prepare, you are preparing to fail.
Quality is not an act, it is a habit.
Well done is better than well said.
Things do not happen. Things are made to happen.
Never complain and never explain.
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.
