apart from the wizard talk.

jk rowling's commencement address at harvard, titled "the fringe benefits of failure, and the importance of imagination" was extremely well written and delivered. dotted with humour and personal experience, this is one video worth watching. she writes so well that almost every other sentence she spoke was capable of  printed on those inspirational quote-cards!

"You might never fail on the scale I did, but some failure in life is inevitable. It is impossible to live without failing at something, unless you live so cautiously that you might as well not have lived at all – in which case, you fail by default."
