I always think of my knowledge the same way a wealthy person thinks of his bank account, all he really knows is addition. My strong analytical abilities invariably attract me to unresolved theoretical problems either at the foundations of physics or at the frontiers of technology. Challenge intrigues and motivates me to discover unique solutions. The act of solving difficult problems not only provides an excellent way of gaining a significant amount of knowledge per unit time but also enables me to derive a deep sense of pride and satisfaction from my hard work.
