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.

If you're going through hell, keep going.

Always desire to learn something useful.

What you do today can improve all your tomorrows.

Never complain and never explain.

Things do not happen. Things are made to happen.

I can, therefore I am.
