The woman behind the popular Harry Potter series was a single mother living on welfare when she wrote the first book of the series. She was rejected by 12 different publishers before selling her book for a measly $4000. The work was an international hit and Rowling went on to write 6 more books for the series, which sold into the hundreds of millions of dollars, and was adapted into a huge blockbuster film franchise. Rowling is now the 13th wealthiest person in Britain, even wealthier than the Queen. Although she has said that she does not plan to write any more books to add to the Harry Potter series, she has written a few short stories and is working on a Harry Potter-related book.
