To know oneself, one should assert oneself.

I can, therefore I am.

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

Things do not happen. Things are made to happen.

If you're going through hell, keep going.

What you do today can improve all your tomorrows.

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

Be gentle to all and stern with yourself.

Well done is better than well said.
