I am earning, let us say, a salary sufficient for my needs. I should be content, but I hear that some one else who I believe to be in no way my superior is earning a salary twice as great as mine. Instantly, if I am of an envious disposition, the satisfactions to be derived from what I have grow dim, and I begin to be eaten up by a sense of injustice. . . . The man who has double my salary is doubtless tortured by the thought that some one else in turn has twice as much as he has, and so it goes on. If you desire glory, you may envy Napoleon. But Napoleon envied Caesar, Caesar envied Alexander, and Alexander, I dare say, envied Hercules, who never existed. You can therefore not get away from envy by means of success alone, for there will always be in history or legend some person even more successful than you are. You can get away from envy by enjoying the pleasures that come your way, by doing the work that you have to do, and by avoiding comparisons with those whom you imagine, perhaps quite falsely, to be more fortunate than yourself.
