Oh, man, chess clock. Brilliant. I just dug out mine and put a new battery in it last month when when the gf challenged me (and she isn't going to do that again -- she hates to lose!) In my experience, things like productivity and diet are easy to change in the short term, but long-term change depends on monitoring and sustained effort. The chess clock is a dead-simple monitoring device, and I'm already habituated to it thanks to many hours spent on chess in high school and college.
