As someone who played tennis at a high-level from kindergarten into my 20s (plus engaged competitively in other sports), I have always believed my drive to do well vis-à-vis the competition (versus others and versus my own past accomplishments), in anything I set out to do, is rooted in a values-structure tracing to my competitive tennis days. Some even argue that tennis players make the best employees! Now, this is not about tennis; it’s about former athletes being global leaders.
But this is not any athlete. Most people play sports as a part of their upbringing. If you are like me, I had my children try out a bunch of different sports to see what they liked, didn’t like, and what could diversify their mindsets. This recreational, low-level sports engagement makes for well-rounded individuals, I believe, but doesn’t make them leaders per se. High-level sports, at least college sports or equivalent, and preferably some kind of professional level where you can at least make some money, is what sets the tone for global leadership.
