Starting from where you are now, you choose. And in choosing, you also choose who you will be. If this sounds difficult and unnerving, it’s because it is. Sartre does not deny that the need to keep making decisions brings constant anxiety. He heightens this anxiety by pointing out that what you do really matters. You should make your choices as though you were choosing on behalf of the whole of humanity, taking the entire burden of responsibility for how the human race behaves. If you avoid this responsibility by fooling yourself that you are the victim of circumstances or of someone else’s bad advice, you’re failing to meet the demands of human life and choosing a fake existence, cut off from your own authenticity.
