  Specific negative and positive self-regarding duties are derived from the more comprehensive duty to oneself to do what one can to lead a good or excellent life. It is probably true, as Aristotle pointed out, that the success of one’s life depends on factors outside of one’s control. If so, then no one can have a duty to lead a good life. Still, excluding the effects of luck, we can say that each human being will have a more or less successful life depending on the decisions they make and the options they pursue. And we can add that each human being has a comprehensive duty to lead a successful life, to the extent that it is within his or her power to do so.
