the manager’s schedule and the maker’s schedule
This rings true for people who are clearly in one camp or another, and probably explains my diary nightmare:
“There are two types of schedule, which I’ll call the manager’s schedule and the maker’s schedule. The manager’s schedule is for bosses. It’s embodied in the traditional appointment book, with each day cut into one hour intervals. You can block off several hours for a single task if you need to, but by default you change what you’re doing every hour.
When you use time that way, it’s merely a practical problem to meet with someone. Find an open slot in your schedule, book them, and you’re done.
Most powerful people are on the manager’s schedule. It’s the schedule of command. But there’s another way of using time that’s common among people who make things, like programmers and writers. They generally prefer to use time in units of half a day at least. You can’t write or program well in units of an hour. That’s barely enough time to get started.
When you’re operating on the maker’s schedule, meetings are a disaster. A single meeting can blow a whole afternoon, by breaking it into two pieces each too small to do anything hard in.”

IAs are a bit of both, so I have a diary cluttered with lots of ‘short’ decision making meetings but I also need to carve out half day (at least) chunks so I can actually design or write stuff. The real GTD challenge for me is keeping my design work going in weeks where I only have scattered time here and there.
