No truly happy person feels the need to stand in front of a mirror and recite that she's happy. She just is.

Do not speak of your happiness to one less fortunate than yourself.

Nobody wants to believe happiness is a choice, because that puts responsibility in their hands

...But if a mirror ever makes
you sad

you should know
that it does
not know
you.

No man is happy who does not think himself so.

Do not feel envious of the happiness of those who live in a fool’s paradise, for only a fool will think that it is happiness.

No one is ever unhappy because of someone else.

No man sees himself in a mirror as he really is, nor any woman.

This fixation on the positive- on what's better, what's superior- only serves to remind us over and over again of what we are not, of what we lack, of what we should have been but failed to be. After all, no truly happy person feels the need to stand in front of a mirror and recite that she's happy. She just is.

Never say anything about yourself you do not want to come true.

Don't spend you life making other people happy. Other people being happy is their problem.

You are concerned with your own happiness and I am telling you that there is no such thing. Happiness is never your own, it is where the ‘I’ is not.

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

No one may force anyone to be happy according to his manner of imagining the well-being of other men; instead, everyone may seek his happiness in the way that seems good to him as long as he does not infringe on the freedom of others to pursue a similar purpose, when such freedom may coexist with the freedom of every other man according to a possible and general law.
