YOU'LL FEEL MUCH BETTER AFTER A GOOD BLEEDING.

I once read this Nietsche quote: "A useless life is a death sentence," or words to that effect. Anyone have any idea which book that was, and what the book entailed? No, I'm not planning to do more petulent whining. I'm outlining a writing project right now, and I want one of the characters to give another character such book. Any help would be appreciated.

How about good self-help books? Can anyone think of a good book to give someone who has suffered a debilitating injury?
