To know oneself, one should assert oneself.

Things do not happen. Things are made to happen.

You never know what motivates you.

If you think you can do it, you can.

I can, therefore I am.

What you do today can improve all your tomorrows.

By failing to prepare, you are preparing to fail.

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

The dog that trots about finds a bone.
