Your question to me helps me increase my focus on how to arrange things so I can do more of the type of thing that's really satisfying in the long run: higher horizons-of-focus stuff. That's why I really appreciated you asking.
I also like Mark Jantzen's signature question: "How did you capture that thought?" I'll sometimes get things done immediately so I don't have to bother putting them into any system, for example. That's one way of capturing a thought, and that question can help remind me to do stuff like that.
