Ahh Dave, the Micro-thinker, and me the Macro-thinker. I had this problem in Economics (my major no less) as well. My professors always told me that they were amazed at some of the theories I could come up with and recognize intuitively, but were equally disappointed at my lack of effort when it came to my motivation to prove them rigorously. I loved macroeconomic theory, hated micro-theory. Definitely a good thing there are both types of us around here.
