I just want to emphasize the trick you outlined because it is the most effective for me. Have something to do? Just get started on it and do a little bit. I don't mean get started on it with the intention to finish it. This is what stops you – fear of actually doing it. So, really, start with the intention to just do a little bit. Tell yourself you're just taking some notes, you'll stop after 10 minutes. Then, do one of two things: (1) stop and do something else or (2) if you find yourself wrapped up in the work, consider allowing yourself to continue. But you must not think of option (2) when you begin. It's not an option.

Zizek once said that in order to get himself to write, he needs to to tell himself that he's just going to take some notes. One of the most productive critical theorists in the world has procrastination problems too, and he gets over them with self-deception. He also schedules every moment of his life though, so don't think one trick is all that's required to be at the top of your field.

Ultimately, I think finding a way to dodge your anxiety entirely is very important. I don't believe in "muscling through".
