If you ask an older adult about their greatest regrets, they’ll probably tell you they regret not spending more time with loved ones, and spending too much time on work. As they near the end of their lives, they attest more and more that relationships matter most. And yet so many of us remain focused on professional goals rather than the relationships closest to us. Hopefully, we can learn from the regrets of others and embrace the power of relationships now as one of the most important aspects of a life well-lived. This is especially important for leaders of mastermind groups as they help each member become the best and most fully realized version of themselves.
