So then, an amended question: given that you do much better solving a problem that you personally have, what happens if you're a person of few desires? Someone who enjoys having a simple life and focuses intently on a few things that matter to them, but doesn't really sweat or even notice many of the things that annoy other people?

It seems like this personality type would be well-suited for entrepreneurship in general, between having a low personal burn rate and being able to focus intently on a topic, but the inability to recognize and get seriously worked up about a problem seems like a killer.
