In case you need an antidote to commencement speeches that tell you to follow your dream to attain success, here's Bobcat Goldthwait's 2009 Commencement address to Hampshire College, in which he exhorts his listeners to abandon success and never stop quitting (and then he says that doing this made him happy and successful). The good stuff starts around the 10-minute mark. Around 14:30, he reminds them all to bathe. It's actually a very nice talk.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
