No matter if you know or not who J. K. Rowling is (although I doubt there's anybody there who hasn't heard of the author of the popular Harry Potter book series), whether you're a student or you had already graduated, or even if you barely remember the times you were studying, her speech at Harvard is a must-see. She addresses the newly graduates at Harvard University, talking about the benefits of failure in life and the importance of imagination for each and every one of us. Whichever path you might chose to take in your carreer and in your life, her words are absolutely inspiring.
