Binder with the keys

I would just get an old-fashioned binder and start with the QuickBooks lists because they're already in place. Print them out, put them in, and then get dividers and say vendors, customers, employees. And then as you think of things, you could just tear a piece of paper because these thoughts come in one ear and go out the other very quickly, and make notes and shove the note in the book. So at least you're that far. It might not be a formal document, but you know when next time you look at the book with time to spare, that's like, that's right, that's why I wrote that. So that's one way to get going.
