To know oneself, one should assert oneself.
The wise does at once what the fool does at last.
Be gentle to all and stern with yourself.
I can, therefore I am.
Leap, and the net will appear.
Know or listen to those who know.
Always desire to learn something useful.
Things do not happen. Things are made to happen.
Be thine own palace, or the world's thy jail.
The secret of getting ahead is getting started.
Change is the only constant. Hanging on is the only sin.
