Welcome to 90% Mental 

90% Mental explores what it means to build a strong mental game “on the court,” at the office, and in life through original essays and interviews with entrepreneurs, leaders, athletes, academics, and sports professionals.

The name is inspired by a quote that has been attributed to hall of fame catcher and legendary Yankees player Yogi Berra. Berra is quoted as saying, “Baseball is 90% mental and the other half is physical.”  While the percentages were clearly made in jest, Berra’s point remains a sound one. While skill, talent, and aptitude play an incredibly important role in success, a well developed mental game can make the difference between good and becoming great. I believe that this isn’t just true in the realm of sports but also in the arenas of leadership, entrepreneurship, and life.

Occasionally, I write extended pieces that synthesize research, experience, and practical insights. These essays are longer form and designed for deeper reading.
