I can, therefore I am.

If you think you can do it, you can.

To know oneself, one should assert oneself.

Either you run the day or the day runs you.

Expect problems and eat them for breakfast.

Always desire to learn something useful.

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

The dog that trots about finds a bone.

The most effective way to do it, is to do it.
