With the conclusion of the tennis Australian Open, the book “The Inner Game of Tennis” comes to mind. It was written back in 1972 by Timothy Gallwey when the mental game was little understood and his approach was considered radical. Now it is commonplace to realise that a game is 95% in the head. Look at the recent tournament in Melbourne. How does someone play brilliantly one set and then completely lose it the next or vice-versa. You see the mental strength of Serena Williams, able to access another gear when things are down. Roger Federer able to stay cool as he knows he has the ability to mentally outlast any other player.
