The happiness of your life depends upon the quality of your thoughts: therefore, guard accordingly, and take care that you entertain no notions unsuitable to virtue and reasonable nature.

In the morning when thou risest unwillingly, let this thought be present - I am rising to the work of a human being. Why then am I dissatisfied if I am going to do the things for which I exist and for which I was brought into the world?

Reject your sense of injury, and the injury itself disappears.

And thou wilt give thyself relief, if thou doest every act of thy life as if it were the last.

Be content to seem what you really are.

Don't go on discussing what a good person should be. Just be one.

Whoever values peace of mind and the health of the soul will live the best of all possible lives.
