Drawing on fifteen years of data from their Marriage365 app, Casey and Meygan Caston have created a refreshingly practical guide to improve any marriage. Their central premise is simple but powerful: most couples don't need more therapy—they just need better habits.
The book's true strength lies in its actionability. The Castons present ten non-negotiable habits that successful couples use to maintain and repair their relationships, with each chapter concluding with probing questions for discussion and self-awareness:
The 10 Habits:
- The KNOWN Position - Daily physical connection and eye contact
- The Weekly Marriage Business Meeting - Aligning on schedules, responsibilities, and priorities
- Love Lists - Showing love in the specific ways your partner wants
- The 60-Second Blessing - Daily affirmations and compliments
- Connection Time - Scheduled weekly fun and laughter together
- Leverage Your Differences - Appreciating each other's strengths and rhythms
- The Codeword - Using conflict as an opportunity to grow
- Unsolicited Apologies - Keeping short accounts and admitting wrongs quickly
- Head. Hands. Heart. Habit. - The power of forgiveness and repair
- The sex talk - Great sex starts with great conversations
The chapters on unsolicited apologies and forgiveness particularly stand out for me, with the Castons noting that "an apology is the closest thing marriage has to a magic wand." Their emphasis on curiosity as "the ultimate relationship hack" and their reminder that "progress matters more than polish" create a safe space for couples at any stage to begin improving their relationship.
"The Marriage Habit" offers hope that with intentionality and the right habits, any couple can create the relationship of their dreams.
