If talent and ability (intelligence) was all learned, then we would all be Gold medal athletes, Major League record holders, mental geniuses and musical Mozart's. Unless of course we chose not to.
I have seen ridiculous vanities before, but this one is down right comical.
I agree, if large brain volume or IQ were a great indicator then I would certainly be the leader of the free world. I am a big, tall man with a head to match, I can hardly find a straw hat big enough to fit on my head when I want to go outside in the Carolina sun and when I joined the Navy straight out of high school my IQ was somewhere inside the top one percent. I am not rich or famous, I am not a great musician or anything of the sort. I have made my living as a technician and salesman and I do telephone sales now. If I had one ten thousandth of the ability of Mozart I would be a great musician because I certainly have spent more time trying to learn the piano than he ever did but was never able to do anything spontaneous. I could only learn through a laborious process to reproduce a string of notes in a beginner sort of style. I have, on the other hand, been blessed with a natural ability to spot con artists such as Obama and recognize them almost instantly as what they really are.
I remember a very good baseball pitching instructor telling me that he (with proper training and hard work) could get any kid to throw a ball 80 miles per hour by the time he was a senior in high school, after that it’s all genetics and no amount of training will significantly increase velocity.
