Never contract friendship with a man that is not better than thyself.

If you try to do too much, you will not achieve anything.

Behave when away from home as though you were in the presence of an honored guest. Employ the people as though you were assisting at an important sacrifice. Do not do to others what you would not like yourself. Then there will be no feelings of opposition to you, whether it is the affairs of a state that you are handling or the affairs of a family.

Unify your attention. Do not listen with your ears, but with your mind. Do not listen with your mind but with your essence.

Acquire new knowledge whilst thinking over the old, and you may become a teacher of others.

Love makes a spot beautiful: who chooses not to dwell in love, has he got wisdom?

One who will study for three years. Without thought of reward. Would be hard indeed to find.
