To know oneself, one should assert oneself.

Either you run the day or the day runs you.

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

Be gentle to all and stern with yourself.

By failing to prepare, you are preparing to fail.

What you do today can improve all your tomorrows.

Things do not happen. Things are made to happen.

Always desire to learn something useful.

It's always too early to quit.
