I’ve long favored notebooks for recording new ideas, meeting notes, to-do’s, etc. As The Organized Mind points out, linear books aren’t the best way to track projects and reminders: 3 x 5 notecards are better. You can sort them, add to them, reconfigure them, whatever. I’m going to try using a Hipocket PDA and also track Read Learning that way.
UPDATE. 10/27/15 I’ve got 3x5s all over now but I can’t bring myself to carry them all around.
