What is a good person? One who achieves tranquillity by having formed the habit of asking on every occasion, "what is the right thing to do now?"

If you wish to live a life free from sorrow, think of what is going to happen as if it had already happened.

Once you know who you are and to whom you are linked, you will know what to do

Men are disturbed not by the things that happen, but by their opinion of the things that happen.

Keep your attention focused entirely on what is truly your own concern, and be clear that what belongs to others is their business and none of yours.

If you see anybody wail and complain, call him a slave, though he be clad in purple.

In prosperity it is very easy to find a friend; but in adversity it is the most difficult of all things.
