Be gentle to all and stern with yourself.

I can, therefore I am.

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

The dog that trots about finds a bone.

Know or listen to those who know.

The secret of getting ahead is getting started.

Quality is not an act, it is a habit.

Do not weep do not wax indignant. Understand.

To know oneself, one should assert oneself.
