Couple of things my Dad said to me in High School come to mind.
I pitched in High School. I wasn't bad but I wasn't all that good either. Dad [and Coach O. for that matter] wanted me to fulcrum off my plant foot, come over the top more and tighten up my delivery. It just didn't feel right. I was a dig and driver like Seaver. If I would have listened to them I would have been able to increase velocity and maybe, just maybe got to go the college for free.
Dad also told me to never pass up a good thing over breast size. In High School there was a very nice girl that liked me. Cute and sweet as could be but she had like...no breasts. So I dated another girl who had breasts but was kind of a wench. She caused me some heartbreak for sure.
