I had some context that didn't work but I really needed them. For example, I use @Errands for any Next Actions I can do when on my way (to home or office). I started using it when put a Post-It with "Check @Errands" in the car where I can see it.
The same story with @Agenda. I needed to remind me of topics I need to discuss when meet a customer on non-regular basis. But I always forget to open it during or even before the meeting (I use Palm). Any ideas of how to remind myself to open it?
