I like the Pomodoro technique. However, despite what this article is saying, I find myself doing all my "fun" tasks at the beginning of my work session, and after maybe an hour or two of that, I can concentrate on the mundane tasks for hours and hours. I wish I knew how to cut down "fun" time; I've tried and I end up not doing anything at all. Writing it down only makes it more appealing to work on; it still bounces in my head -- so I don't write creative ideas down at all. Writing it down is just enough impetus to work on those tasks instead of the mundane tasks we all must do in life.
