After many decades of fighting procrastination the most important thing I have learned is that you cannot analyze yourself out of procrastination. You cannot read articles to solve your procrastination problem. The only thing that works is to start the work. I wish there were something else I could tell you, but that's it. Just open the book, open the editor, open the document, whatever.

Now, that said, you may be burnt out, or you may not actually have to do the thing you're putting off. That's different. I'm talking about something you know you have to do (or else painful and undesirable consequences), but you're avoiding starting it. It's a trap. Just find any way to start. Do a bit, don't get down on yourself if you only do a bit. It's better than nothing.
