Over the past few months, I have most assuredly become a candidate for rotator cuff surgery.  This development is due to the countless number of pitches I have thrown to my son during batting practice in preparation for the upcoming high school baseball season.  Pitch after pitch he works to fine-tune his swing.  He also began throwing, working on his pitching mechanics. What started out as a fun backyard activity when he was three, has become an obsession.  I’m a bit biased, but rarely have I seen this kind of discipline and single-mindedness in someone his age. This is mythical thinking.
