I'm working on a todo list with a Seinfeld calendar. My take is that there are only three categories: Work, Home, Personal. There are two buckets of tasks, Short term and long term. You'd move long term tasks into the short term when you start working on them. At the beginning of the week, you'd move the tasks from the short term into the day of the week that you planning to work on them. The catch is, you can only work on three tasks per day. Each task has an associate cost or reward. Get enough done you can reward yourself a nice purchase. Or don't get things done and you'll owe your friend a fancy dinner. There are more details and reasoning behind it, but my idea is to keep the number of tasks small so we can get them done and keep the calendar line going. Other todo lists I used I ended up putting too much on there and it turned into list of lists.
