A 4 color pen + cheap amazonbasics moleskine knockoff Black = facts. numbers, locations, new edicts, etc Blue = thoughts. musings. edge cases I think of during meetings but don't want to derail over, etc green = events (after work social, conferences, etc) red = todo It's not perfect (ex: I usually write the details of meetings such as time/location and add a red star with "TODO: enter meeting X into calendar" but the line between a meeting an event can blur. Is an intern presentation an event or a meeting? My main distinction is meetings are mandatory, events can be moved. (Ex: I won't schedule a doctor's appointment during a client meeting. I would list the day there's an evening drinks session as a time I could meet the doctor) It's not perfect, but the general idea is that the notebook is to store things until the end of the meeting - then they go into my calendar, into my todo list, or onto my whiteboard as problems to be brainstormed.
