I think that's one thing a lot of people don't give a lot of thought to. Preparation is great, but having supplies, weapons, ammo, that sort of thing doesn't help you if you don't change your mindset as well. The month's worth of food being gone in a week is a perfect example. As soon as it becomes a problem, you need to start planning on how you're going to make what you have last as long as you can, how you're going to add to it (hunting, gathering, etc) and get an idea of what you need for your activity level.
