Athletes – lessons learned

The majority of world record holding, professional athletes are genetical gifted individuals. Each eventually realizes that time is the only opponent they could not defeat.  They all turn in their jersey and ask themselves, What’s next? Who am I? How do I find a new passion for my life?

My plan is to provide the male baby Boomer answers to those same three questions by encouraging them to always value their life’s playing minutes
