I can, therefore I am.

If you can dream it, you can do it.

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

It's always too early to quit.

By failing to prepare, you are preparing to fail.

The wise does at once what the fool does at last.

Expect problems and eat them for breakfast.

If you're going through hell, keep going.

Things do not happen. Things are made to happen.
