Instead of being in a stressful task-switching state of mind, take your next task, let everything else go, and just be in the moment with this one task.  Let yourself be immersed in this task by letting go of the feeling that you need to quickly rush through it – that you need to move on to the next task waiting for you.  There will always be a next task, because that’s the nature of TO-DO lists – they’re never-ending.  So let those later tasks come later.  Just be 100% in this one task, like it’s your entire world.  Bottom line: Slow down.  Breathe.  Review your commitments and goals.  Put first things first.  Do one task at a time.  Start now.  Take a 5-minute break in an hour.
