I basically have three contexts: @Work, @Waiting, and @Home. If it's a work phone call I'll make it when I'm at work, regardless of whether that's at my own desk, in a few minutes between meetings, or from my cellphone at the airport. It's still "work".Originally Posted by webagogue
The overhead of looking down the list to separate out the things that I can/can't do in a particular subcontext is trivial compared with maintaining separate subcontexts and remembering to look at them all.
What I do find is that I tend to group activities by type. So if I have to make an urgent phone call I'm more likely to work through the rest of the calls on my list. If I have to write an e-mail, I'll pick the rest of them off the list (my NA list is typically between 20 and 40 items at any time).
It's not "pure" GTD, but it does work for me. And that's what counts at the end of the day.
