World-famous pianist Sir Stephen Hough is also a composer and writer and has been named by The Economist as one 'Twenty Living Polymaths'.   In his frank and engrossing memoir, Enough, he recounts his unlikely journey from an unmusical Cheshire home to the stage of Carnegie Hall by the age of 21. He candidly shares his teenage nervous breakdown, struggles with sexuality and religion, unconventional parents, and the teachers who inspired and discouraged him.
