If you think you can do it, you can.
The wise does at once what the fool does at last.
What you do today can improve all your tomorrows.

To be a good loser is to learn how to win.
Expect problems and eat them for breakfast.
Be kind whenever possible. It is always possible.
If you're going through hell, keep going.
