In life our first job is this, to divide and distinguish things into two categories: externals I cannot control, but the choices I make with regard to them I do control. Where will I find good and bad? In me, in my choices.

Keep silence for the most part, and speak only when you must, and then briefly.

What is a good person? One who achieves tranquillity by having formed the habit of asking on every occasion, "what is the right thing to do now?"

Any person capable of angering you becomes your master.

An ignorant person is inclined to blame others for his own misfortune. To blame oneself is proof of progress. But the wise man never has to blame another or himself.

Wisdom means understanding without any doubt that circumstances do not rise to meet our expectations. Events happen as they may. People behave as they will.

Cowardice, the dread of what will happen.
