Let every action aim solely at the common good.

Most of what we say and do is not essential. If you can eliminate it, you'll have more time, and more tranquillity. Ask yourself at every moment, 'Is this necessary?'

All that is from the gods is full of Providence.

Whosoever does wrong, wrongs himself; whosoever does injustice, does it to himself, making himself evil.

It is not the weight of the future or the past that is pressing upon you, but ever that of the present alone. Even this burden, too, can be lessened if you confine it strictly to its own limits.

Our life is what our thoughts make it.

Practice really hearing what people say. Do your best to get inside their mind.
