4-creteria model for choosing what to do. I think I don't understand this model. Let's say I have 'Call My brother re: organizing a party for mom' at my action list. I'm at my office without access to the phone. Why should I think about the context creteria (@office) where I can't call my brother if I know that's the most important thing I have to do? I mean if I follow this model I would call my brother only when I have access to the phone. And what happens if I don't?
