Well, this aged well! I'm glad to see this very reasonable take so far.
One thing that I don't see mentioned is a "go-bag" or "bug out bag", which I find to be one of the more useful preparations. Have a bag with some clothes, your documents, medication, whatever you might need if you need to leave your house in a couple of minutes notice for a couple of days. Super useful even if it's not a total life and death emergency, but you need to see or help someone, and won't know for how long. A lot of good advice here about what to put in it though! And a lot of useful advice on good skills to have.
One other small note: always have a roll of paper towels and toilet paper in your trunk in a bag. Just trust me on this one, you'll thank me later.
