@Longstreet, again, I have no argument with anything you are saying, or for that matter anything you have said about time-blocking. Your approach is entirely consistent with GTD. I don't use the calendar to the extent you do, but I have come to think of GTD as a pretty big tent. I think the only thing that would be truly antithetical to GTD would be deliberately managing things in your head. My concern about what @Jan Ernest described, though, is that it sounds like he is keeping all next actions in one single list and then scheduling each and every one of them or otherwise managing his entire next action list in his calendar. I don't think that's quite consistent with the GTD system. Which, again, isn't a problem... unless you're trying to do GTD. I think it would be pretty hard to manage the long list of actions created by capturing everything meaningful in one's life that way. So... if you were expecting an argument, I am afraid I am going to disappoint you. It wouldn't be the first time I've disappointed someone. And it won't be the last, I'm sure.
