The most expensive mistake in business might not be a bad hire, a bad deal, or a missed investment.
It might be how you treat your marriage while you are building the business.
If you are an entrepreneur, marriage can quietly get the leftovers: leftover time, leftover attention, leftover patience, leftover energy. The business gets the mission statement, the quarterly retreat, the best hours, the best strategy.
The person you love gets whatever is left after the calendar is done with you.
I know that pattern because I lived it.
You will see the five rhythms that helped me stop giving Carrie whatever energy was left: the weekly huddle, the do-over, date night, a shared marriage vision, and the simple calendar rules that protect love before business eats it.
The entrepreneur marriage mistake nobody prices in
Divorce can take 50% on paper.
But the emotional cost can hit harder than any financial loss. Fighting, bitterness, resentment, distance, kids feeling the tension, health getting worse, joy disappearing from the house. That is expensive even before lawyers get involved.
For the first eight years of my marriage, I had a vision for my company and rhythms for my executive team.
For my marriage? Nothing.
No real plan. No consistent rhythm. No shared vision. I was a New York Times bestselling author and a mediocre husband. That sentence is not fun to write, but it is true.
The biggest lie Carrie ever called me out on was when I said, “I’m doing this for you, babe.”
I was missing family events. I was hardly present. She felt like a single mom. Her answer cut through the whole performance: “I didn’t ask for any of this. I asked for you.”
That is the part many business owners miss. More money does not automatically create more connection. More success does not automatically create more presence. If the business is getting all the structure and the marriage is getting scraps, wealth starts to feel hollow.
Start with a weekly relationship huddle
Carrie and I created a weekly relationship huddle.
It is 45 minutes to an hour every week. No phones. Sometimes coffee. Sometimes a record playing. The point is simple: create a safe place for the important stuff before it becomes an emergency.
I ask her, “How present am I as a husband?”
I call it the present score.
A 10 is great. A nine means a small tweak. An eight means I am off track. A seven might as well be zero, because she is probably not going to say zero. Seven is the floor.
The first few meetings were rough. That is normal. If you have not checked in for months or years, there is a backlog. It is like ignoring the books for six months and then trying to clean up everything in one sitting.
But the huddle gives hard conversations a container.
Without it, the hard stuff comes up in the car, in bed when you are tired, in front of the kids, or at the worst possible moment. With it, you have a time and place where both people know, “This is where we tell the truth.”
We also created a tool called the do-over.
If I say something dumb, if I am hangry, if I am temporarily meaner than sane, I can ask for a do-over. It acknowledges that I would behave differently if I could run the moment again.
I wish I had known that on our honeymoon in New York City in 2002. We fought over a $7 chocolate-covered strawberry and a bag Carrie wanted to buy. I thought both were ridiculous. I ruined the moment trying to be right about a few dollars.
That is not financial intelligence. That is scarcity wearing a math costume.
Date your spouse on purpose
You fell in love on purpose. Stay in love on purpose.
That means dating your spouse every week, not once a year on your anniversary. And “What do you want to do tonight?” does not count. That is a meeting about a meeting.
I started taking responsibility for date night. I keep an app on my phone with restaurant ideas, hikes, concerts, comedy, unique experiences, and random recommendations from friends.
If a buddy says, “We did this amazing thing last weekend,” it goes in the app.
I keep question decks in my bag, in the drawer by the espresso machine, and even near the sauna. I write out questions before date night. Real questions, not “How was your day?”
Questions like:
- How did your family handle money when you were growing up?
- What have you always wanted to do but never told me?
- What would make this Christmas the best one we have ever had?
- What would help you feel more seen right now?
Think of your marriage like your most important client relationship. If you only called your best client once a year and said, “So what do you want to do?” you would lose the client.
Carrie is my most important client. I tell my team that. Do not move those meetings. Make it a priority.
That is not a cute line. It is a standard.
Your business has a vision. Your marriage deserves one too
In August 2009, everything felt like it was falling apart. Business, the economy, finances, all of it.
Carrie looked at me and said, “Why do you take care of everyone before you take care of us? What about us? This is not what you promised.”
She was right.
I had values for the business. Retreats for the company. Time, money, and attention for the mission.
But not for my family. Not for my marriage.
On August 7, 2009, I asked Carrie for a do-over. We created guidelines. I would not travel more than four nights per month. If I did, I would take a day off during the week.
I would be done by 6 p.m. on four out of five work days. No computer in the bedroom.
Then we created a vision.
Mine was to be a premier romantic and extraordinary husband. Not decent. Not good enough. Extraordinary.
That meant I had to learn. We flew to Chicago for a commitment ceremony and interviewed three couples we believed had the best marriages. Carrie interviewed the women. I interviewed the men. Then we all had dinner and asked for advice.
I had no problem telling an entrepreneur to get a vision for the business. So why was I winging the most important partnership in my life?
That question changed the standard.

Always have something on the books
For almost 15 years, Carrie and I have had the 14-night rule: 14 nights away from the kids per year. Just the two of us.
Some people say, “Put your kids first.”
I disagree. So did the couples we interviewed.
Put your marriage first and your kids get better parents. Put your marriage first and when the kids leave the house, you still have each other. Put your marriage first and you get a better life along the way.
The trip does not have to be Copenhagen. It can be a weekend away. The point is anticipation.
When something is on the calendar, you get to look forward to it. You text about it. You plan outfits. You pick restaurants. You are doing life together before you even leave.
If it is not on the calendar, it usually gets swallowed by the business.
That is how marriage gets leftovers. Not because you do not care. Because the business has structure and the marriage has hope.
Hope is not a strategy.
Give the part of yourself that matters most
For years, I held back.
Not in an obvious way. On paper I was doing plenty. Dates, money, family, business, the responsible stuff.
But there was a part of me I kept in reserve.
What if I give everything I have and she does not love me back? What if she knows me better than anyone and rejects me? Would that mean I am not lovable?
That fear was running in the background.
I would show up 90%, but the 10% I was protecting was the 10% that mattered most: vulnerability, softness, openness, emotion, presence.
When I finally stopped protecting that part, something changed. The more I gave, the more I could give. The more I gave, the more I could receive.
Love compounds.
And this is why entrepreneur marriage is not separate from wealth. Your marriage is part of your wealth. Your relationship is part of your quality of life. If you get the money right but lose the person sitting next to you, you did not win.
I have had money without the magical marriage. It sucked.
Carrie is my co-creator, my celebrator, my confidant, my rock, my favorite person, and the love of my life. That is not something you get from a finance book.
In prosperity,

Frequently Asked Questions
Why is marriage so important for entrepreneurs?
Marriage affects energy, focus, health, decision-making, and quality of life. If the business grows while the marriage gets leftovers, success can create resentment instead of freedom.
What is a weekly relationship huddle?
A weekly relationship huddle is a scheduled conversation with no phones where you talk about presence, the calendar, upcoming decisions, hard conversations, and the future you are creating together.
How can business owners stop giving marriage leftovers?
Give the marriage the same kind of structure the business gets. Put date night on the calendar, create a shared vision, schedule trips, ask better questions, and protect those commitments like client meetings.
Can a better marriage improve wealth?
Yes, because wealth is not just money. A stronger marriage can improve clarity, resilience, energy, confidence, and the quality of the life your money is supposed to support.
