You know, Murphy's Law and all, if you do all this preparation it's just going to mean you'll end up sticking around for another decade. But in any case. I'd suggest not using a computer at all for this kind of thing. It's waaaaay too easy for files on a computer to disappear, get lost, or become otherwise unable to access. And it's so impersonal. Even if you print it out, it's just toner on a page. Get a decent journal and write up a list in your own handwriting. If your wife and kid are sentimental, they'll enjoy having it. If not, they'll be like damn it, why didn't Ballzz just type this up so it was legible.
