If you can dream it, you can do it.
To be a good loser is to learn how to win.
Be gentle to all and stern with yourself.
By failing to prepare, you are preparing to fail.
Well done is better than well said.
It's always too early to quit.
Expect problems and eat them for breakfast.
Be kind whenever possible. It is always possible.
Never complain and never explain.
If you think you can do it, you can.
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.
