I can, therefore I am.

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

If you think you can do it, you can.

The dog that trots about finds a bone.

What you do today can improve all your tomorrows.

Be thine own palace, or the world's thy jail.

If you can dream it, you can do it.

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

Without hard work, nothing grows but weeds.
