I can, therefore I am.

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

Leap, and the net will appear.

If you can dream it, you can do it.

To know oneself, one should assert oneself.

By failing to prepare, you are preparing to fail.

Be gentle to all and stern with yourself.

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

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