You're lucky. I'm always conscious of myself — in my mind. Painfully conscious. - Jean-Paul Sartre

"So this is hell. I'd never have believed it. You remember all we were told about the torture-chambers, the fire and brimstone, the "burning marl." Old wives' tales! There's no need for red-hot pokers. Hell is — other people!"

Our aim is precisely to establish the human kingdom as a pattern of values in distinction from the material world. But the subjectivity which we thus postulate as the standard of truth is no narrowly individual subjectivism, for as we have demonstrated, it is not only one's own self that one discovers in the cogito, but those of others too. Contrary to the philosophy of Descartes, contrary to that of Kant, when we say "I think" we are attaining to ourselves in the presence of the other, and we are just as certain of the other as we are of ourselves. Thus the man who discovers himself directly in the cogito also discovers all the others, and discovers them as the condition of his own existence. He realizes that he can't be anything unless others recognize him as such. I cannot obtain any truth whatsoever about myself, except through the mediation of another. The other is indispensable to my existence, and equally so to any knowledge I can have of myself.

But I must finally realize that I am subject to these sudden transformations. The thing is that I rarely think; a crowd of small metamorphoses accumulate in me without my noticing it, and then, one fine day, a veritable revolution takes place.
