The Inner Game of Tennis may be the great sleeper of the sports shelf: nominally a tennis book, in practice a study of the inner obstacles that stand between ability and performance – which is why so many of its devotees have never held a racquet. The same method went on to serve golfers, skiers, musicians and managers, and that portability tells you where the real subject lies.
For UK listeners, audio suits the material unusually well: a book about what happens inside your head, delivered directly into it. Listen before a match, a recital or a difficult Monday morning; the lessons are built to transfer, which is precisely how Gallwey carried the Inner Game from tennis to music to work.
