To learn and from time to time to apply what one has learned - isn't that a pleasure?

I used to listen to what others said, and expect them to act accordingly. But nowadays, I listen to what they say, and then observe what they do.

Even if I could, I would not exahnge their virtues for my own. And that is why they are intent on learning from me.

Fine words and an insinuating appearance are seldom associated with true virtue.

Look for an occupation that you like, and you will not need to labor for a single day in your life.

Knowledge is recognizing what you know and what you don't.

Ask yourself constantly, "What is the right thing to do?" Behave toward everyone as if receiving a great guest.
