I can, therefore I am.

If you think you can do it, you can.

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

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

What you do today can improve all your tomorrows.

By failing to prepare, you are preparing to fail.

Never complain and never explain.

If you're going through hell, keep going.

The dog that trots about finds a bone.
