That's probably why the author has beginner tasks on the whiteboard like making a bed, washing the dishes, etc. It's hard to imagine having such tasks throughout one's entire life while struggling with procrastination.
That is what makes it a method that requires very little time and energy, and therefore something that can be sustained over the long term.
The part where I end up finishing the whole thing doesn't always happen, but breaking it down into chunks that I can power my way through even if I'm in the worst mood with the worst working conditions at least lets me accomplish a small thing and get a better sense of the task for the next time I try. Sometimes "Add 5 Items" actually turns into "Add 2 items and realize you only need 7 total items."
Some of my procrastination is "I haven't started the task because I can't completely visualize it, I can't completely visualize it because I haven't started the task."
Starting to write this comment was easy, because I knew what I was going to say before I started typing; but writing a book seems impossible, because I can't hold the whole thing in my mind at once. Funny thing is, this comment has changed and expanded since I started it, but since I didn't expect that, there was no uncertainty and I didn't hesitate to start it. Now if I could just find a way to fool myself about bigger projects.
