ADHD
I think maybe the reason priority heap time management has been working well for me is: it lets my ADHD brain go where it wants. As soon as this project stops being what I most want to do with my time, I'll stop. And maybe come back to it. Or maybe not.
I'm not attached to the idea of completing it. I'm not going to push myself to get it done. I won't regard it as a failure if I abandon it.
I suspect I will get it working eventually, though, because the web isn't getting any less annoying.
