28. — Jealousy is in a manner just and reasonable, as it tends to preserve a good which belongs, or which we believe belongs to us, on the other hand envy is a fury which cannot endure the happiness of others.

Envy is an indicator that alerts you if you’re being honest with yourself. If you can look at someone who has things you don’t and say, “You know what. I really don’t want that,” you know you’re in a good place. If you say you don’t want something but don’t mean it, envy will eat away at you. What it’s telling you is that you really do want it but are afraid to work for it.

Envy consists in seeing things never in themselves, but only in their relations. If you desire glory, you may envy Napoleon, but Napoleon envied Caesar, Caesar envied Alexander, and Alexander, I daresay, envied Hercules, who never existed.

Jealousy is always a mask for fear: fear that we aren’t able to get what we want; frustration that somebody else seems to be getting what is rightfully ours even if we are too frightened to reach for it. At its root, jealousy is a stingy emotion.

Make a list of five people you care about, but also feel competitive with. Come up with at least one reason that you’re envious of each one: something they’ve achieved, something they’re better at, something that’s gone well for them. Did that achievement actually take anything away from you? Now think about how it benefitted your friend. Visualize everything good that has come to them from this achievement. Would you want to take any of these things away if you could, even knowing that they would not come to you? If so, this envy is robbing you of joy. Envy is more destructive to you than whatever your friend has accomplished. Spend your energy transforming it.

People's envy shows how unhappy they feel; their constant attention to the doings of others how bored they are.

Jealousy is perhaps the most involuntary of all strong emotions. It steals consciousness, it lies deeper than thought. It is always there, like a blackness in the eye, it discolours the world.

Jealousy is both reasonable and belongs to reasonable men, while envy is base and belongs to the base, for the one makes himself get good things by jealousy, while the other does not allow his neighbor to have them through envy.

Now envy and antipathy, passions irreconcilable in reason, nevertheless in fact may spring conjoined like Chang and Eng in one birth. Is Envy then such a monster? Well, though many an arraigned mortal has in hopes of mitigated penalty pleaded guilty to horrible actions, did anybody ever seriously confess to envy? Something there is in it universally felt to be more shameful than even felonious crime. And not only does everybody disown it, but the better sort are inclined to incredulity when it is in earnest imputed to an intelligent man. But since it's lodgement is in the heart and not the brain, no degree of intellect supplies a guarantee against it.

Jealousy is that pain which a man feels from the apprehension that he is not equally beloved by the person whom he entirely loves.

One day, I realized with all these people I was jealous of, I couldn’t just choose little aspects of their life. I couldn’t say “I want his body”, “I want her money”, “I want his personality”. You have to be that person. Do you actually want to be that person, with all of their reactions, desires, their family, their happiness level, their outlook on life, their self-image? If you’re not willing to do a wholesale, 24/7, 100% swap with who that person is, then there is no point in being jealous

Jealousy is like a raging toothache. One cannot do anything when one is jealous, not even sit down. Once can only come and go. Back and forth.

Live with a steady superiority over life-don't be afraid of misfortune, and do not yearn after happiness; it is, after all, all the same: the bitter doesn't last forever, and the sweet never fills the cup to overflowing. It is enough if you don't freeze in the cold and if thirst and hunger don't claw at your insides. If your back isn't broken, if your feet can walk, if both arms can bend, if both eyes can see, and if both ears can hear, then whom should you envy? And why? Our envy of others devours us most of all.

With the wise man, what he has does not cease to be enjoyable because some one else has something else. Envy, in fact, is one form of vice, partly moral, partly intellectual, which consists in seeing things never in themselves but only in their relations
