You should always be ready to apply these two rules of action, the first, to do nothing other than what the kingly and law-making art ordains for the benefits of humankind, and, the second, to be prepared to change your mind if someone is at hand to put you right and guide you away from some groundless opinion.
The universe is change; life is your perception of it.
The fraction of infinity, of that vast abyss of time, allotted to each of us. Absorbed in an instant into eternity. The fraction of all substance, and all spirit. The fraction of the whole earth you crawl about on. Keep all that in mind, and don't treat anything as important except doing what your nature demands, and accepting what Nature sends you.
At dawn, when you have trouble getting out of bed, tell yourself: I have to go to work—as a human being. What do I have to complain of, if I'm going to do what I was born for—the things I was brought into the world to do? Or is this what I was created for? To huddle under the blankets and stay warm?
The honest and good man ought to be exactly like a man who smells strong, so that the bystander as soon as he comes near him must smell whether he choose or not.
Do the things external which fall upon thee distract thee? Give thyself time to learn something new and good, and cease to be whirled around.
Another does wrong. What is that to me? Let him look to it; he has his own disposition, his own activity. I have now what Universal Nature wills me to have, and I do what my own nature wills me to do.
You need to avoid certain things in your train of thought: everything random, everything irrelevant. And certainly everything self-important or malicious. You need to get used to winnowing your thoughts, so that if someone says, "What are your thinking about?" you can respond at once (and truthfully) that you are thinking this or thinking that.
Try how the life of the good man suits thee, the life of him who is satisfied with his portion out of the whole, and satisfied with his own just acts and benevolent disposition.
