This is great advice for overcoming procrastination and I use it daily. It has significantly improved the way that I work. I think I learned of the trick from GTD, or possibly Pragmatic Thinking and Learning. A TODO list by itself isn't helpful for me -- in fact, in can increase my procrastination by seeing a giant list of tasks because it's just so overwhelming.

What has worked is coupling the task with the next immediate action. Depending on the level of procrastination, this next immediate action does not have to be a grand vision. It is often as simplistic as "open the lid to your laptop", then, "open a text editor", then "think of the file you need to edit", then "type hello world three times" (just to get me to start writing __something__). Passing that initial hurdle usually gets me to the desired state of flow.

Similarly, I now have the following written at the top of my TODO list at all times: "Direct the Rider. Motivate the Elephant. Shape the Path." This psychology comes from Switch by Dan Heath and Chip Heath, and it's hugely impacted my outlook on work, especially as a researcher.
