There's another quote that struck me that I thought I'd put up here on my blog:
geeks are able to memorise almost any trivial fact, apart from the trivia of their own lives.
So, the trick is, tell a nearby geek the trivia of your life, and they'll remember it better than you do. And vice-versa.
Ha! That sounds so silly, but so true. My wife is a remember-everything type of person, and I'm *always* asking her what we have planned for the weekend. If it weren't for her (and my Palm Tungsten T2, which I've been using a lot more lately), I wouldn't have any clue what was going on in my own life.
