Others in the pursuits after happiness or pleasure must commonly seek those sources of it which they cannot enjoy without some inconvenience to the rest of their fellow creatures; hence they have their imaginary happiness so much soured by Envy, Jealousy, or self-disapprobation that they find themselves dissappointed.

The happiness which is lacking makes one think even the happiness one has unbearable.

The unhappy person resents it when you try to cheer him up, because that means he has to stop dwelling on himself and start paying attention to the universe. Unhappiness is the ultimate form of self-indulgence. When you're unhappy, you get to pay a lot of attention to yourself. You get to take yourself oh so very seriously.

Whatever affection we have for our friends or relations, the happiness of others never suffices for our own.

The unhappy are egoistic, spiteful, unjust, cruel, and less capable of understanding each other than fools. Unhappiness does not bring people together but draws them apart, and even where one would fancy people should be united by the similarity of their sorrow, far more injustice and cruelty is generated than in comparatively placid surroundings.

To make others less happy is a crime. To make ourselves unhappy is where all crime starts. We must try to contribute joy to the world. That is true no matter what our problems, our health, our circumstances. We must try.

Unless one is happy, one cannot bestow happiness on others.

It's madness to envy other people's happiness. Happiness doesn't come of the peg, it has to be made to measure.

I think we are only bitter about other people's joy in direct proportion to our commitment to keep joy from ourselves.

Unhappiness comes from wanting what others have. Happiness comes from wanting what you already have.

Our idea of happiness may be the very thing that’s preventing us from being happy.

The expectation that someone else will, in the long run, make us happy is the perfect way to end up unhappy.

If one only wished to be happy, this could be easily accomplished; but we wish to be happier than other people, and this is always difficult, for we believe others to be happier than they are.

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