Seneca

‘What progress have I made? I am beginning to be my own friend.’ That is progress indeed. Such a people will never be alone and you may be sure he is a friend to all.

Nothing, to my way of thinking, is a better proof of a well ordered mind than a man’s ability to stop just where he is and pass some time in his own company.

What you think of yourself is much more important than what others think of you.

It is one thing to remember, another to know.  To remember is to safeguard something entrusted to the memory.  But to know is to make each thing one's own, not depend on the text and always to look back to the teacher.  "Zeno said this, Cleanthes said this."  Let there be space between you and the book.

"To greed, all nature is insufficient."

Religion is regarded by the common people as true, by the wise as false, and by the rulers as useful.

The Fates lead him who will, him who won't they drag.

Throughout the whole of life one must continue to learn to live and what will amaze you even more, throughout life you must learn to die.  Seneca (Roman philosopher) 

As long as you live, keep learning how to live.

Most powerful is he who has himself in his own power.

Choose as a guide one whom you will admire more when you see him act than when you hear him speak.
