Harry Bernstein was a total failure when he wrote his bestselling memoir, The Invisible Wall. His prior forty (forty!) novels had been rejected by publishers. When his memoir came out, he was ninety-three years old. A quote from him: “If I had not lived until I was 90, I would not have been able to write this book, God knows what other potentials lurk in other people, if we could only keep them alive well into their 90s.”
