Expect problems and eat them for breakfast.

To know oneself, one should assert oneself.

The dog that trots about finds a bone.

Know or listen to those who know.

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

If you think you can do it, you can.

Quality is not an act, it is a habit.

Never complain and never explain.

The wise does at once what the fool does at last.
