What you do today can improve all your tomorrows.

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

To know oneself, one should assert oneself.

If you're going through hell, keep going.

Be gentle to all and stern with yourself.

Always desire to learn something useful.

Expect problems and eat them for breakfast.

If you think you can do it, you can.

The dog that trots about finds a bone.
