I invest for a living. I like to collect data and graph it and analyze it. I learn math for fun. I try not to become too attached to my ideas, so I like to imagine that my models of how the world works is populated by variables, not constants, that can change. I believe that efficient economies are most productive and the most fertile ground for achievement for a people. I focus much on cycles of various types, why they occur, their histories and the cycles most relevant to us now. The most important non-religious book I've read is Strauss & Howe's The Fourth Turning, which may be more than 10 years old, but I had waited all my life for someone to write about generational cycles.
