" Most effective altruists are not saints but ordinary people like you and me, so very few effective altruists claim to live a fully ethical life. Most of them are somewhere on the continuum between a minimally acceptable ethical life and a fully ethical life. That doesn’t mean that they are constantly feeling guilty about not being morally perfect. Effective altruists don’t see a lot of point in feeling guilty. They prefer to focus on the good they are doing. Some of them are content to know they are doing something significant to make the world a better place. Many of them like to challenge themselves, to do a little better this year than last year. "
