"Writing all the time"

Upon hearing of a friend's plan to listen to Terry Pratchett audiobooks during all 24 hours in the car on an upcoming road trip, I flipped to the Pratchett interview in The Wand and the Word. I love this exchange with Leonard Marcus:

Q: Do you have a daily work routine?

A: I assume that what I'm doing is writing all the time--even though I'm actually doing something else. When you are stuck and you go out into the garden to pull weeds, you are still writing. Part of you is. ... [W]riting isn't just sitting in front of the keyboard, although that's a fairly vital part of the process. You're still being a writer when you are reading or making notes, or just enjoying yourself.

Weeding, reading, and making notes? Check, check, and check. I think I've just quadrupled my productivity so far this week.
