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

The dog that trots about finds a bone.

I can, therefore I am.

To know oneself, one should assert oneself.

If you can dream it, you can do it.

Always desire to learn something useful.

What you do today can improve all your tomorrows.

If you think you can do it, you can.

Expect problems and eat them for breakfast.
