Well, the verdict seems quite clear: area of focus by 3 to 0, and maybe the reason why my 20K list never appealed to me: I tried to do everything too permanent and it became too stale, detached from the actual facts of my life.

In fact, this doubt came to me this morning while I was revamping my projects; I once heard some GTD coach say that the common misconception was treating as projects things that are in fact AOF. I didn't think that it applied to me, but this morning I've discovered that I've been doing that a lot. Then, when I reached the repair stuff, I wasn't clear.

So thank you all for your great advice, which also works for me as a reaffirmation. I think now I have a better grasp of the 20K because, in fact, I feel like going through it and taking it to a new level. Thank you
