What Do You Care What Other People Think? (1988) is ghost written by Ralph Leighton the son of Feynman’s Caltech collaborator Robert Leighton, who also collaborated with Feynman on writing Surely you must be joking (1985). One third of the 250 pages of the book consist of short, humorous, and easy reading stories. But some of them also contain intensely moving lessons, for example the chapters dealing about his wife who suffered from tuberculosis. These first 80 pages are already worth reading the book!
