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

To know oneself, one should assert oneself.

Be gentle to all and stern with yourself.

If you're going through hell, keep going.

Expect problems and eat them for breakfast.

Things do not happen. Things are made to happen.

By failing to prepare, you are preparing to fail.

The dog that trots about finds a bone.

Know or listen to those who know.
