I selected all sentient perceptual experience as my ultimate ethical value after studying philosophy and completely rebuilding my ethical beliefs without previous dogmas. It came as a result of thoughts that emerged around the being-for-itself concept in Jean-Paul Sartre's Being and Nothingness book and Peter Singer's work. Consequently I have become an act utilitarian, vegan and an effective altruist. The concept has had a profound impact on my significant long-term decisions. I am confident that the world would be significantly better for everyone if everyone valued sentient experience, maximised positive perceptual experience and minimised negative perceptual experience.
