There are so many ways to keep track of things these days -- online calendars, all kinds of personal organization and list-making apps, and automated reminder memos. I tend to get irritated with automatic memos; when they go off, I turn them off immediately and then sometimes forget about the task the reminder was supposed to be reminding me about. I think there's nothing more useful than a physical notebook with a list written in it. Having an old-fashioned list sitting right in front of you where you can see it seems to work so well -- you can add to it whenever a thought comes to you and scribble notes easily. I personally like making a new list every day and crossing tasks off as I go; if an item doesn't get done, it gets moved to the next day's list.
