I've lost my list!

I am definitely a list-maker. I have to-do lists at work, in my purse, next to my home PC, on my phone, grocery lists, etc. But my main list is the one in my purse. When I'm at work and think of something I have to do on the way home, or at home, that's where I write it down. If I'm at home and think of something I need to do at work the next day, that's where I write it down.

And now I've lost it. I know I haven't remembered everything that I still need to do, and it bugs me. I remember a few things I had already crossed off (e.g. call Irene), and still need to do (buy a new printer cartridge), but it's the others that will have me worrying for a while.
