Practice makes perfect. That just about sums it up. It's a simple idea, but a thesis that Matthew Syed goes through in convincing detail. Based upon his own experience as the number 1 table tennis player in the UK followed by a career as a sports journalist, Syed explains how the talent of sporting geniuses like Tiger Woods and Roger Federer can be put down to hours and hours of practice. He also tackles how positive thinking links in with his theory and how it affects the tricky subject of why African runners seem to dominate in distance running and African-Americans seem to dominate in sprinting. Accessible, clear and convincing.
