Day 3: Nothing But Kindness
Treat your spouse with the same level of customer service you get from your favorite Barrista at Starbucks. Imagine your marriage is a business deal, and your spouse is a million-dollar client. Borrow a corporate mission statement and make it work to improve your marriage: Exceed expectations. Be polite, cheerful, and considerate. Throw in some perks. The "customer" is always right when you're spending five days to a better marriage.
Happy married people surround you, you have a positive attitude, and you're providing your spouse with nothing but kindness.
