Also, when you're changing tasks, it's important to reclaim your attention from the previous task, so it can be fully reallocated. More than just crossing off a task and taking a break, I take a moment to really notice my progress---what I accomplished, learned, implications, etc---and then write it down. This little bit of reflection feels good (a small win!) and helps me close the task out from my attention. So then, I'm refreshed and ready for the next thing (after a glass of water, play with the puppies, etc). The long term result is that I can look back at any day and see what I actually accomplished. Which is pretty sweet.
