I do think this is pretty fundamental, but what I liked was the idea of thinking about "categories" (using the author's term). It presents a slightly different way of thinking of how to prepare, at least for some people. I know many here are way beyond this level of preparedness, and I knew it when I posted this...

Here's what the author says towards the end, and I thought it was a good idea for getting a different view on how to prepare:
When doing your own list, one way to think about it is by categories. That’s mostly how I do it. For example, think of a general area such as ‘kitchen’ and then list priorities in that category. Other general categories included shelter, clothing, food and water, tools, sanitation, security, transportation, etc… think ‘categories’ and then narrow it down within each category. If you are just starting – then start with food and water!
To each his own, but for many people, this may be their first introduction to thinking about preparedness...
