Noel and Suelin: thanks for your excellent examples of what "wild success" means.
Smartin: I might look for an alternative phrase, too. Hmm: "an 'I'm so happy' outcome", "deep satisfaction", "something to celebrate", "smooth joy", "cool", "energizing", "a real contribution", "worthy of congratulations", "fabulous", "magical", "inspiring", "up a level", "great results", "what I hoped for", "admirable", "uplifting", "freeing", "a real accomplishment", "a surprise","great value", "a hoped-for result".
KLW: I think you seem to be following a fallacy: that if you envision something and think up a way to accomplish it then you have to do it. It may work for you, but I don't like the idea of purposely not envisioning something just to avoid that (though doubtless I do that subconsciously).
As I see it, GTD is not about getting done all the things you think of. Rather, it's about choosing a bunch of more important things and getting them done. I think it's great to have a large number of options and then choose the most important ones out of those. In theory at least, that means you're using your time very effectively.
Here's one approach: for a project, visualize three levels of outcomes: wild success, ordinary success, and minimal effort. For example, if you're organizing a dinner party, for "setting the table", minimal effort might be announcing to the guests "you can each get yourselves forks and things out of the top drawer in the kitchen". After doing this visualization, then you can choose among four options: not doing the project at all, or doing it at one of the three levels. You can consider what other projects you might be leaving aside if you put a lot of effort into this one. You can ask yourself "how much time do I want to put into this?" It's OK to choose to do many things at the minimal or ordinary level. Some things you might choose to put more effort into and aim for a great result.
I think it's good to visualize wild success even if you don't choose to do the extra work, because there's a possibility that you might go for it. You might think up ways of doing it that don't take a lot of effort. You might find ways to incorporate parts of your vision of wild success even if not the whole thing. You might keep the vision of wild success in mind while doing a moderate amount of work, and find it inspiring and energizing. You might decide that for this particular project wild success is worth putting a lot of effort into. If you don't even envision it, you might miss those various opportunities.
You have 24 hours in a day in any case. The question is whether you're spending your time on things that are worth that time. Not burning the dinner is more important than detailed setting of the table.
