We suffer more often in imagination than in reality. [We must learn to control and focus the force of our imagination on the good, bright side so it is positive and constructive helping ourselves and others, rather than let its force focus on the bad, dark side so it is negative and destructive hurting ourselves and others!]

The guilt of enforced crimes lies on those who impose them.

You should rather suppose that those are involved in worthwhile duties who wish to have daily as their closest friends Zeno, Pythagoras, Democritus and all the other high priests of liberal studies, and Aristotle and Theophrastus. None of these will be too busy to see you, none of these will not send his visitor away happier and more devoted to himself, none of these will allow anyone to depart empty-handed. They are at home to all mortals by night and by day.

We should conduct ourselves not as if we ought to live for the body, but as if we could not live without it.

Nothing is more disgraceful than that an old man should have nothing to show to prove that he has lived long, except his years.

No action will be considered blameless, unless the will was so, for by the will the act was dictated.

You must know for which harbor you are headed, if you are to catch the right wind to take you there.
