Bobcat Goldthwaite commencement address: don't be afraid to quit, success is overrated:
In case you need an antidote to commencement speeches that tell you to follow your dream to attain success, here's Bobcat Goldthwaite'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.
