Jean-Paul Sartre - Existentialism and Human Emotions

I am responsible for everything, in fact, except for my very responsibility, for I am not the foundation of my being. [...] To make myself passive in the world, to refuse to act upon things and upon Others is still to choose myself, and suicide is one mode among others of being-in-the-world. [...] "Why was I born?" or curse the day of my birth or declare that I did not ask to be born, for these various attitudes toward my birth-i.e, toward the fact that I realize a presence in the world-are absolutely nothing else but ways of assuming this birth in full responsibility and of making it mine.
