No matter how much you have planned for today, you need to try to keep things simple. If you toss too many details into the mix, you are bound to get overwhelmed, which could make you very cranky! This day has a lot of potential to be very enjoyable, so it would be a shame to stress yourself out. Avoid overcomplicating things or trying to make them exactly how you want them to be. Good enough is good enough. Save perfection for another time.
