I think there's an unaddressed point in the book that should include "for the average person with average physical/emotional/intellectual capacity 10k hours - give or take - of _deliberate_ practice should make you a master". This intuitively makes sense to me, and what I took away from the book. I guess others took away other things and if you want to fault the author for that I'm not going to stop you. It's also fashionable to over-analyze everything these days so some won't be satisfied unless there are exact data points involved it should warrant throwing out the whole book and to which I would say to them sometimes it's about the notion rather than it's exactness. In any way the book is interesting and still worth a read.
