Don't overcomplicate your contexts, is my general advice.
90% of my time, I'm home or at work; I've defined my contexts there into some fine levels of granulation: @Laptop, @email, @Internet.

But since so little of my time is 'out and about' - I have just one. "Errands"

When I go home at night or when I have something minor (like grab dinner), I take a quick look at my errands list.

If I have the extra moment, I look at my "Thinking" context too - just in case I want to give my mind something to chew over on the way home.

If it has to be done on my way home, then it is a calendar item (with the time.) I probably should have OF schedule this - but to be honest, the act of looking at my calendar is a good think.

TL;DR - Basically, i look at my phone on the way out the door at the "errands" context to see if there's anything I need to pickup.
