" The greater purpose of the Pomodoro Technique is to avoid multitasking, and wasting mental capital switching between tasks and backtracking, while you try to find where you were.  This frequently will result in one step forward, and one step backward, and after a couple of hours, you might find that you’ve only made minimal progress across all your tasks. Complete attention and focus for twenty-five minutes, no small amount of time, will allow you to build momentum and really make way through your information. "
