What you do today can improve all your tomorrows.

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

To know oneself, one should assert oneself.

You never know what motivates you.

If you think you can do it, you can.

By failing to prepare, you are preparing to fail.

Never complain and never explain.

The dog that trots about finds a bone.

Well done is better than well said.
