No man is able to make progress when he is wavering between opposite things.

It is no easy thing for a principle to become a man's own unless each day he maintains it and works it out in his life.

Control thy passions lest they take vengence on thee.

Never say about anything, "I have lost it," but only "I have given it back." Is your child dead? It has been given back. Is your wife dead? She has been returned.

It is your own convictions which compels you; that is, choice compels choice.

Consider first the nature of the business in hand; then examine thy own nature, whether thou hast strength to undertake it.

No living being is held by anything so strongly as by its own needs. Whatever therefore appears a hindrance to these, be it brother, or father, or child, or mistress, or friend, is hated, abhorred, execrated.
