First learn the meaning of what you say, and then speak.

No man is free who is not master of himself... Is freedom anything else than the power of living as we choose?

In a word, neither death, nor exile, nor pain, nor anything of this kind is the real cause of our doing or not doing any action, but our inward opinions and principles.

There is but one way to tranquility of mind and happiness, and that is to account no external things thine own, but to commit all to God.

Make it your business to draw out the best in others by being an exemplar yourself.

If anyone is unhappy, remember that his unhappiness is his own fault... Nothing else is the cause of anxiety or loss of tranquility except our own opinion.

Imagine for yourself a character, a model personality, whose example you determine to follow, in private as well as in public.
