Do wrong to thyself, 25 do wrong to thyself, my soul; but thou wilt no longer have the opportunity of honouring thyself. Every man’s life is sufficient. But thine is nearly finished, though thy soul reverences not itself but places thy felicity in the souls of others.

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. But then thou must also avoid being carried about the other way. For those too are triflers who have wearied themselves in life by their activity, and yet have no object to which to direct every movement, and, in a word, all their thoughts.

Through not observing what is in the mind of another a man has seldom been seen to be unhappy; but those who do not observe the movements of their own minds must of necessity be unhappy.
