Napoleon Hill said it best: “No two minds ever come together without thereby creating a third, invisible intangible force, which may be likened to a third mind.”

He called it the Mastermind Principle, one of the most powerful ideas in his legendary book Think and Grow Rich.

Here’s the gist: Surround yourself with smart, driven people, and your potential skyrockets. You don’t just get ideas—you get better ideas. Solutions you never thought of appear. Opportunities you never noticed become obvious.

I’ve experienced this firsthand.

For years, I’ve invested in high-end mastermind groups and top-tier coaching. And I’ll be honest: the checks I’ve written for some of these groups have been enough to make a grown man wince. But here’s the kicker: those investments have paid for themselves many times over.

The ideas, strategies, and feedback I’ve gotten from being in a room with other ambitious entrepreneurs—and guided by a coach who knows how to push me—have been game-changers for my business and my life.

Here’s what most people miss about coaching and mastermind groups: It’s not just about what you learn. It’s about who you learn it from and who you learn it with.

When you surround yourself with people who are smarter, more experienced, or just thinking bigger than you, it forces you to level up.

You can’t help but grow.

So, let me ask you: Who’s in your corner? Are you surrounding yourself with people who challenge, inspire, and hold you accountable? Or are you trying to go it alone, hoping you’ll figure it out eventually?

If you want to make a leap—whether in your business, personal life, or both—you need a mastermind group and a coach who can see what you can’t and push you to reach your full potential.

Napoleon Hill wasn’t wrong: Success is rarely a solo act.

Kick butt, make mucho DEEnero, and remember: your “third mind” could be the key to everything you want.
