It is easier to make a list to what does not work. Some people like to set their clocks a few minutes ahead on the theory that they will be less likely to be late. This was a favorite strategy in my wife's family. Unfortunately, it is hard to fool yourself and people often quickly adjust, knowing that the real time is 10 minutes earlier than what the clock shows. Similarly, calendar reminders such as "your deadline is 10 days from now" rarely help all that much.
