Anyone have any experience with getting like a filofax? Could that work? I used to have one that was a wallet as well and well..then at least you do take it with you everywhere. It was 10 years ago though and I was even more rebelling against organization then than now, so I ended up forgetting to look in it or write stuff down in it.
Right now, I rely somewhat on calendars for far in the future social events, and other than that on that stomach feeling FemmeUrbane was describing *grin*
