If any method depends on me initiating some action, it won't work for me. My brain will not only say "No", but it'll also often just shut up, not give any feedback and proceed to procrastinate.

For me, procrastination has some similarities to addiction. If I'm on a streak, I can maintain it. If I fail once, it's really hard to get back to it. I may be productive for a week, but sooner or later, something is going to happen that will allow me to procrastinate. When this happens, I'm like an addict, I'm not satisfied with a small dosage, and all limits are off. I know I should be working instead of watching Youtube. I don't want to do it, and I know I will regret it. All this happens while I'm typing "youtube.com" into my browser's address bar.

Various methods work on various people. Experiment and try different methods. Don't confuse it with trying multiple implementations of one method - if you tried two to-do list apps and it didn't work for you, skip the to-do lists and move to something else. My method is body doubling, but YMMV. Once you find a method that works for you, revisit previous productivity methods - they may supplement your productivity
