For me, it's something I ran across in one of DA's books -- can't remember if it was GTD or Making It All Work. Anyway, it's the problem that when you're trying to concentrate on Task A, your mind is likely to keep distracting you with popping up all these other tasks that you really ought to be thinking about. That's a BIG problem for me! The GTD solution is to PLAN for that to happen -- to Capture all those ideas, write them down, and then get right back to Task A at hand!
