This is what the world honors: wealth, eminence, long life, a good name. This is what the world finds happiness in: a life of ease, rich food, fine clothes, beautiful sights, sweet sounds. People who can't get these things fret a great deal and are afraid, wear themselves out rushing around on business, spend night and day scheming and scrutinizing. Man lives his life in company with worry, and if he lives a long time, then he has spent that much time worrying. This is a callous way to treat the body.
In order that people may be happy in their work, these three things are needed: they must be fit for it; they must not do too much of it; and they must have a sense of success in it . . . a sure sense that so much work has been done well, and fruitfully done, whatever the world may say or think about it.
