Albert Camus said this quote

I have realized that we all have plague, and I have lost my peace. And today I am still trying to find it; still trying to understand all those others and not to be the enemy of anyone. I only know that one must do what one can to cease being plague-stricken, and that's the only way in which we can hope for some peace or, failing that, a decent death. This, and only this, can bring relief to men and, if not save them, at least do them the least harm possible and even, sometimes, a little good.
