To know oneself, one should assert oneself.

Quality is not an act, it is a habit.

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

Be gentle to all and stern with yourself.

Never complain and never explain.

Know or listen to those who know.

If you've got a talent, protect it.

Do not weep do not wax indignant. Understand.

By failing to prepare, you are preparing to fail.
