Of course, she doesn't need one now...

J.K Rowling delivered the commencement address at Harvard University this year, and it is a stunning, beautiful, thought-provoking read.

Not only did the world's richest and most powerful (and one of my favorite) literary figure talk about failure, but she also detailed the life-changing day job that she worked in her early 20s.

"One of the greatest formative experiences of my life preceded Harry Potter, though it informed much of what I subsequently wrote in those books. This revelation came in the form of one of my earliest day jobs. Though I was sloping off to write stories during my lunch hours, I paid the rent in my early 20s by working in the research department at Amnesty International's headquarters in London."

Dare to be inspired, and take 15 minutes to read the speech.
