It's best to use either a constant simple log or an occasional detailed log: I occasionally note nearly everything I do during a single day, so I know how I use my time. But most days I use a brutally simple time-log: one sheet of paper, divided into two sides. One side gets a tick-mark every time I do something I'd normally procrastinate on; one side gets a mark every time I procrastinate instead. That's as complicated as it needs to be (but I have a pretty simple job).
