Clear out your schedule and set aside your expectations: this is going to be a fickle kind of day, and you need to be as flexible as possible. It's a day to toss out the rule book and just let things go along their merry way. You won't be disappointed. But if you struggle against the tide of the day and stubbornly try to stick to what you had planned, you'll experience a lot of frustration. Become more passive, and you will learn an awful lot about the world around you.
