I don't know about you but I'm a list maker...so..i make a list in great detail (to ensure i waste as much time as possible) and then i start at the top and work my way down, after each task i take a short 5 min break.Go for a smoke..or air..if you don't smoke...do some jumping jacks...read one of the comics from the news paper, listen to a song you love, write a naughty limerick? Then after i do said pleasurable activity i force my way on to the next task until the list is done. It feels really good to actually cross it off as done, and the little fun reward is also nice for when you have completed something. Worth a shot even if your not much of a list maker.
