chunks + big picture (push vs flow)
Yes, I agree micro chunking is a great trick.
Who has a cat knows they won't try to jump something they don't believe they can. Our brain doesn't also.
So a BIG THESIS might not get you to jump, but half a page might. Each big travel starts with a first step, and one step at a time can get you far.
On the other side, you will want some FLOW on the work. You will not want to make a big thing out of each single step all the way. Somewhere along the way, you want some sort of FLOW to happen. Then, putting a foot after the other stops being the focus point (even if that was need in the beginning), and now you are just walking towards your destination almost effortlessly, and enjoying the view and the ride itself, as much as you are thrilled about the idea of arriving to your destination.
I believe that flow is easier to get, if you can see yourself after the Big Thing is done. David says "You won't be able to do it until you see yourself doing it", and I would add the question: "Can you picture you life after you have accomplished that? Can you really visualize it, even in the small things? How is it? What is your routine? How does it feel?" - and if you dive into that picture over and over again, until it's part of your thinking, and becomes so normal, that's when you find space for the flow, and each step starts to feel just the normal think to happen, and not a battle against inner resistance. That's when real magic happens...
