You spend 10 years bouncing a ball, bring a smile to some, a look of wonder from others all while doing what you love. These are sacred teachings and no one is harmed in the process. Sounds like an accomplishment that matters to me.
Some guys spend 10 years in university, because they wanted to learn a profession, to be useful to their community, others spend 10 years bouncing a ball. You can see the consequences when you turn 50 and time to accomplish something is running out.
