Be gentle to all and stern with yourself.

To know oneself, one should assert oneself.

Things do not happen. Things are made to happen.

Either you run the day or the day runs you.

By failing to prepare, you are preparing to fail.

Always desire to learn something useful.

If you've got a talent, protect it.

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

Expect problems and eat them for breakfast.
