Our notions about happiness entrap us. We forget that they are just ideas. Our idea of happiness can prevent us from actually being happy. We fail to see the opportunity for joy that is right in front of us when we are caught in a belief that happiness should take a particular form.

It is the very pursuit of happiness that thwarts happiness.

Sooner or later in life everyone discovers that perfect happiness is unrealizable, but there are few who pause to consider the antithesis: that perfect unhappiness is equally unattainable. The obstacles preventing the realization of both these extreme states are of the same nature: they derive from our human condition which is opposed to everything infinite. Our ever-insufficient knowledge of the future opposes it: and this is called, in the one instance, hope, and in the other, uncertainty of the following day. The certainty of death opposes it: for it places a limit on every joy, but also on every grief. The inevitable material cares oppose it: for as they poison every lasting happiness, they equally assiduously distract us from our misfortunes and make our consciousness of them intermittent and hence supportable.

Similar to the way we are led along in life by the endless pursuits of pleasures, we are led along, even saved by the endless revelation of pain. This in itself may not be a happy thought, but it is a reminder of how relative, always, are our perceptions of misery and joy.

The desire to feel happy or think positively all the time hinders many people's authentic existence. It lowers resilience.

"Ending Notions of Happiness

Each of us has a notion of how we can be happy. It would be very helpful if we took the time to reconsider our notions of happiness. We could make a list of what we think we need to be happy : "I can only be happy if ... " [...] Where did these ideas come from? Are they reality? Or are they only your notions? If you are committed to a particular notion of happiness, you do not have much chance to be happy.
Happiness arrives from many directions. If you have a notion that it comes only from one direction, you will miss all of these other opportunities because you want happiness to come only from the direction you want."

It is a terrible thing to be happy! How pleased we are with it! How all-sufficient we think it! How, being in possession of the false aim of life, happiness, we forget the true aim, duty!

We have everything we need to be happy, but we aren't happy. Something's missing.

No, the opposite of happiness is hopelessness, an endless gray horizon of resignation and indifference.3 It’s the belief that everything is fucked, so why do anything at all?

If we only wanted to be happy, it would be easy; but we want to be happier than other people, and that is almost always difficult, since we think them happier than they are.

my original view was closest to Aristotle’s — that everything we do is done in order to make us happy — but I actually detest the word happiness, which is so overused that it has become almost meaningless. It is an unworkable term for science, or for any practical goal such as education, therapy, public policy, or just changing your personal life.

Sooner or later in life, everyone discovers that perfect happiness is unrealizable, but there are few who pause to consider the antithesis: that perfect unhappiness is equally unobtainable . . . Our ever-sufficient knowledge of the future opposes it and this is called in the one instance: hope.

The search for happiness is one of the chief sources of unhappiness.

Nothing is more fatal to happiness than the remembrance of happiness.
