Working Hard or Hardly Working?

"For this reason, I cannot call the man industrious, if I hear this only, that he reads and writes; and even if a man adds that he reads all night, I cannot say so, if he knows not to what he should refer his reading. For neither do you say that a man is industrious if he keeps awake for a girl; nor do I. But if he does it for reputation, I say that he is a lover of reputation. And if he does it for money, I say that he is a lover of money, not a lover of labor; and if he does it through the love of learning, I say that he is a lover of learning. But if he refers his labor to his own ruling power, that he may keep it in a state conformable to nature and pass his life in that state, then only do I say that he is industrious."

(Epictetus, Discourses, 4.4.41.43)
