Being happy. (I happen to be wildly successful at that.)

I think a lot of people think that if they are "successful" it will make them happy instead of just being happy. Jobs, a mate, cars, houses, etc can't make you happy. (They can make you unhappy though.)

That said, it probably a good thing that the gene pool contains whatever it is that makes some people driven to leave a perfectly good family and sail halfway around the world to discover some new country in order to feel "successful".
