And this is the simple truth - that to live is to feel oneself lost. He who accepts it has already begun to find himself, to be on firm ground. Instinctively, as do the shipwrecked, he will look around for something to which to cling, and that tragic, ruthless glance, absolutely sincere, because it is a question of his salvation, will cause him to bring order into the chaos of his life.

You love the accidental. A smile from a pretty girl in an interesting situation, a stolen glance, that is what you are hunting for, that is a motif for your aimless fantasy. You who always pride yourself on being an observateur must, in return, put up with becoming an object of observation.
