Cal talks with one of the greatest tennis players of all time about the attitude and strategies that can guide us all through the different stages of reinvention. There are few people on the planet more equipped to talk about this evolution than Maria, who left Russia at the age of six with her dad to come to America and play tennis. Her dad had roughly $700 when they arrived. Maria went on to the IMG Academy, and on to win Wimbledon at the age of 17. She won all the Grand Slam events before retiring early this year, but, more than that, she became a model, UN Ambassador, owner of a candy company, art collector and investor. She has achieved mastery on many levels – and offers us all tips on how to get to where we want to go next.
