I can, therefore I am.

To know oneself, one should assert oneself.

Do not weep do not wax indignant. Understand.

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

Things do not happen. Things are made to happen.

After a storm comes a calm.

What you do today can improve all your tomorrows.

The secret of getting ahead is getting started.

Leap, and the net will appear.
