JK Rowling uses rejection letters to inspire budding authors

JK Rowling has posted a series of rejection letters she received in the years prior to the release of the Harry Potter series in a bid to inspire the next generation of authors.

The successful author insists the letters, posted yesterday, are for "inspiration, not revenge," after her fan base requested she release them.

While the letters posted are for her first novel Cuckoo’s Calling, Rowling said she also has a small stockpile of rejection notes for Harry Potter, which has gone on to collectively sell more than 400 million copies worldwide.

"I had nothing to lose and sometimes that makes you brave enough to try," she wrote in a tweet to fans.

Rowling admitted in one of the letters she was even advised to take a writing course.

"I regret that we have reluctantly come to the conclusion that we could not publish it with commercial success," one of the letters read.

Despite fans requesting the author release copies of her Harry Potter rejection letters, Rowling insists they are "in a box in my attic."
