For me, the weekly review is that magic. During the weekly review, I make sure everything I want to do is on my lists. When my lists aren't current or comprehensive, I don't use them because I can't trust them. But the "brain dump" I do during my weekly review is always the magic key for me. I have a daily planning session as well where I "brain dump" the little things and keep on top of my lists. When I get everything out of my mind and into my system, I am able to focus because I am not pre-occupied with worry.
