Reminds me of Steve Blank's post "You Can't Take It With You". Congrats, you might have some deep, unique understandings that might give you a unique insight into the world, but if you haven't offered it up to others in a way that can be retained or utilized, it's worth nothing. In this way, you are a selfish little piglet.

Ph.D's are let into the ether to be consumed and used for the world. Some more efficiently than others, but nonetheless, their research undoubtedly allows for a better world than your own, internal "a-ha" moments.
