I’ve got to agree with a lot of your points, Merlin. For me, using GTD for about 6 months, the key is breaking projects down into next actions. Rather than have an amorphous goal, which resembles a road map with two points but no line connecting them, now I have steps along the route. The nature of my work (writing) makes this easier than for many other people, since I don’t have meetings to make decisions, don’t delegate (drat!), and have fixed deadlines. But GTD has made it easier to manage multiple projects - writing several books at once, writing articles and manuals at the same time, etc.
