For work, I'm a poker player. It might not last forever, but it but it's still challenging and pays the bills, and the freedom fits quite nicely with my lifestyle - to stay up late and sleep until noon, to take off on last minute trips to Europe or across the Pacific.
Scuba diving, travel, whitewater rafting, running, poker, games, wine, wine tourism, trivia, Belgian/craft beer, alpine skiing, Crossfit, Sporcle, NHL hockey.
Reading, mostly nonfiction, programming politics, economics.
Fun. I'm interested in fun.
