J.K. Rowling
When J.K. Rowling began writing Harry Potter, she probably did not expect the series to become a Hollywood blockbuster and make her one of the wealthiest people on our list. Rowling never expected to be famous and tries to separate that factor of her life from her ordinary, everyday activities.
In order to keep her life as quiet as possible, Rowling actually uses her husband’s last name in her private life, which is very clever when you have a surname name as recognizable as hers. Rowling explains “Many parts of my life are perfectly ordinary, one could even call it boring, but that’s what I like about it”.
