Do what you love. "Success" is often improperly applied, as I'm convinced that as long as you do what you actually like doing (chores notwithstanding), then any "success" you achieve doing that is just an added bonus.
And it wouldn't hurt if that which you love doing somehow adds value to yourself and your surroundings.
