Asimov was afflicted with an even worse condition, he was an arrogant ass.
But hey, if being an arrogant ass, or douchebag, or drunk, etc., meant I didn't read an author or listen to a musician then I wouldn't read or listen to much.
Sometimes I think the less we know about and author's and other artist's personal life the better off we are.
I remember reading the first volume of Asmiov's autobiography and being fascinated by the man but then I grew up and realized he was less than admirable, but still a good writer.
I met Assimov in 1967 on a six hour train ride to NYC, my seat mate. He was a munchkin, I am 6’2”, I think that he suffered from small mans syndrome.
