backpack the night before so I don't have to rely on myself to remember to
bring it. I have a separate backpack or zippered bag for each of a few
activities; for example, a backpack I bring to choir practice, so that I have
all the stuff for choir already collected in one place and can just pick it up
and go, or maybe add one more thing I need on a specific day. (That's the way
I do it; that's not GTD or non-GTD.)
I might put it in my home actions list and put an asterisk next to it to
indicate that it's urgent. The action would be to put it into my backpack.
Or I might (very likely) not trust myself to look at my home actions list
between now and the meeting, and I might set my watch to beep to
remind me (at a time when I think I'll be at home) or I might use
a special reminder (for things that only come up occasionally)
such as attaching a note to the outside of my backpack, on the
handle, where I'll see it when I put the backpack away.
If I knew where the document was, and especially if I needed to
bring several things to the meeting, I might put a list of things to
bring on the calendar beside the appointment. I don't usually do
that since I don't have much room on my paper calendar.
The reason I'm more likely to do it if there are several things
to bring is that I'm more likely to remember to look at the
calendar thinking "what are those things I need to bring?"
if there are several, not just one. Or, I could set my watch to
beep shortly before the time I expect to leave, to remind me to
bring the things.
