Book excerpt: A REESE'S BOOK CLUB PICK "A hands-on, real talk guide for navigating the hot-button issues that so many families struggle with."--Reese Witherspoon Tired, stressed, and in need of more help from your partner? Imagine running your household (and life!) in a new way... It started with the Sh*t I Do List. Tired of being the "shefault" parent responsible for all aspects of her busy household, Eve Rodsky counted up all the unpaid, invisible work she was doing for her family -- and then sent that list to her husband, asking for things to change. His response was... underwhelming. Rodsky realized that simply identifying the issue of unequal labor on the home front wasn't enough: She needed a solution to this universal problem. Her sanity, identity, career, and marriage depended on it. The result is Fair Play: a time- and anxiety-saving system that offers couples a completely new way to divvy up chores and responsibilities. Rodsky interviewed more than five hundred men and women from all walks of life to figure out what the invisible work in a family actually entails and how to get it all done efficiently. With four easy-to-follow rules, 100 household tasks, and a series of conversation starters for you and your partner, Fair Play helps you prioritize what's important to your family and who should take the lead on every chore from laundry to homework to dinner. "Winning" this game means rebalancing your home life, reigniting your relationship with your significant other, and reclaiming your Unicorn Space -- as in, the time to develop the skills and passions that keep you interested and interesting. Stop drowning in to-dos and lose some of that invisible workload that's pulling you down. Are you ready to try Fair Play? Let's deal you in.
