    90% of the Time You Have With Your Kids Is Already Gone by Age 18

    This stat changed my life. I lost my dad at 12, so I already knew time was precious. Then I learned that by 18, 90% of your in-person time with your kids is already gone.

    90% of the Time You Have With Your Kids Is Already Gone by Age 18

    90% of your time with your kids is gone by age 18. This stat changed my life. It might change yours too.

    In 2021, I'd just earned an award for building a 7-figure program. And I got invited into an inner circle of people way more successful than me.

    I sat there. I listened. I watched.

    And I saw people who had everything I thought I'd been chasing. The money. The status. The numbers.

    But most of them didn't have a life I wanted.

    I built my business for a different reason. I wanted to take care of my family. But somewhere along the way, I started equating success with revenue. Those two things are not the same. That room taught me that.

    I lost my dad at 12. I already knew time was precious.

    Then someone told me this stat. By the time your child turns 18, 90% of your in-person time with them is already gone. Not someday. Right now. As you read this.

    It changed everything.

    I decided I just wanted to be a good mom. And that had nothing to do with revenue. It had everything to do with time.

    So I started asking a different question. Not "how do I grow faster?" Or "how do I make more money?" But "how do I get more time with my kids?"

    That one question rewired my entire business.

    I stepped back from the growth playbook. Not because I couldn't do it. Because I finally understood what it would cost.

    You don't need a million dollars to learn this lesson. You need to look at this chart and ask yourself one honest question: what am I trading my time for?

    Because time is the only resource you never get back.
