Mastermind groups have gained tremendous popularity in recent years, but the concept isn't new. Introduced by Napoleon Hill in his classic book "Think and Grow Rich," the mastermind principle revolves around the idea that when two or more people come together to focus on a common goal, their combined intelligence and energy create solutions far beyond what an individual could achieve alone.

A mastermind group is essentially a peer-to-peer mentoring circle where individuals share their challenges, brainstorm solutions, and provide support. It's not just about problem-solving but also about building meaningful connections with others who are just as driven and passionate about growth.
