I tried Autofocus as a replacement for my current system for getting stuff done, and so far it works a lot better than GTD (though I can't say that I was using GTD properly, for example, I couldn't bring myself to do regular reviews). The main benefit for me was its ability to handle long-term thinking / gestation tasks, mostly due to not treating them as enemies to be crossed off the list as soon as possible. And it requires very little willpower to run.
I just had an extremely simple but promising theory of why work is aversive!
Work is the stuff you tell yourself to do. But sometimes you tell yourself to do it and you don't, because you're too tired, engaged with something else (like playing a computer game), etc. This creates cognitive dissonance, which associates unpleasantness with the thought of work. (In the same way cognitive dissonance causes you to avoid your belief's real weak points, it causes you to avoid work.) Ugh fields accumulate.
The solution? Only tell yourself to work when you're actually...
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
