J.K Rowling is amazing, inspiring, and I'm glad she exists. This isn't actually a book (surprise!), but instead the graduation speech from a Harvard convocation she spoke at. She speaks of failure, of low points, and how imagination is what the world truly needs. It was also very well illustrated (the version I borrowed at least), and I found myself screenshotting pages to use as my iPad wallpaper. The only problem was that it was over in 20 minutes.
