There's a lot missing from that. How do you track things you are waiting for or that will take many steps over potentially months? How do you look at how much is going on in your life and decide how to trim that if needed? How do you use that inbox to judge whether you're working toward things you want? Where do you put things that you would like to do at some point but not right now?

Again, that's what a lot of people miss. When you have everything in front of you, you can look at it as a whole and say, "Alright, what do I want to be different?"
