The most productive and, next to JK Rowling, richest writer in the world is James Patterson.
If you don’t recognize the name, he is the author of Don’t Blink and The Postcard Killers, as well as 48 other books that have been bestsellers in the past 10 years.
By almost any measure, Patterson is a hugely successful writer. But he doesn’t have the attributes that one would typically expect: a brilliant mind, a passion for his work, etc.
