Great observation! Isn't it true that the geniuses of this world have very often been afflicted with mental abnormalities? Take the most brilliant mathematicians, engineers, scientists; so many of them faced such problems. There indeed seems to be some connection between the mind's capacity to innovate and create and its capacity to suffer delusions and obsessions. Take examples of Gödel, Turing, Tesla, Hemingway, etc. http://dsc.discovery.com/tv-shows/curiosity/topics/mad-geniu...
