It is absurd to divide people into good and bad. People are either charming or tedious.

The happier people can be, the unhappier they are.

There is no such thing as a perfectly happy or perfectly unhappy man in the world. One has more happiness in his life and another more unhappiness, and the same circumstance may produce widely different effects on individuals of different temperaments.

People don't know when they are happy. They're never so unhappy as they think they are.

A happy person isn’t someone who’s happy all the time. It’s someone who effortlessly interprets events in such a way that they don’t lose their innate peace.

Oh, how unbearable is a happy person sometimes!

You can be happy or you can be unhappy. It's just
according to the way you look at things.

People are too complicated to have simple labels.

"Everyone is a mass of contradictions. There are no "types" of people,"

The world of the happy man is a different one from that of the unhappy man.

He is like everyone else, a compound of strange and inexplicable contrasts, and this is what the writers of novels and plays will never understand; they make their characters all of a piece. But people are not like that. There may be ten different people in one man, and sometimes all ten appear within a single hour (Wednesday 7 December 1853).

The most unhappy people in the world are those who face the days without knowing what to do with their time. But if you have more projects than you have time for, you are not going to be an unhappy person. This is as much a question of having imagination and curiosity as it is of actually making plans.

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.

Each of us is sometimes a cretin, a fool, a moron, or a lunatic. A normal person is just a reasonable mix of these components, these four ideal types.
