I can, therefore I am.

To be a good loser is to learn how to win.

It's always too early to quit.

Expect problems and eat them for breakfast.

Begin to be now what you will be hereafter.

Always desire to learn something useful.

If you're going through hell, keep going.

What you do today can improve all your tomorrows.

The most effective way to do it, is to do it.
