"A man can stand a lot as long as he can stand himself. He can live without hope, without friends, without books, even without music, as long as he can listen to his own thoughts." -Axel Munthe
The Swedish psychologist wrote his book of memoirs, The Story of San Michele, in part because he could no longer sleep. "Man was built to carry his own cross, that is why he was given his strong shoulders," Munthe wrote, "but a man cannot live without sleep. When I ceased to sleep I began to write this book, all milder remedies having failed. It has been a great success, so far as I am concerned."
