At work I use two memo pads with "to-dos" or "action items" along with sticky notes all over my desk with various reminders and more action items. Hopefully by next year I can also have use these sticky notes developed by a British company that uses "intelligent" paper embedded with a programmable built-in alarm clock that can flash or beep.
Nerds say what? What. Office managers everywhere say "Ah, hell no. Stick to your Staples sticky notes."
