Sam,
You seem like a nice guy, and if you don't really need the money, why not think about a social service to give you the satisfaction of giving something back to the world. I know of people of independent means who spend a lot of time helping out in old people's homes and hospices etc. These institutions always need support, and you would still have time to follow your dream. Maybe it would help put your dream in perspective. Good luck in whatever you decide.
