Damon's second major piece of advice to the MIT graduates was to keep listening. He acknowledged that the world wants to hear their ideas — good and bad — but cautioned against the arrogance of thinking graduation means you've finished learning. He shared that he'd recently retaken a philosophy course he first took at Harvard at age 19, and pointed graduates to resources like MIT OpenCourseWare, Wait But Why, and TED.com. He even couldn't resist a jab: 'I'm told there's even a Trump University. I have no earthly idea what they teach there.' The deeper point was about intellectual humility — he quoted President Obama's recent Howard commencement address: 'Democracy requires compromise, even when you are 100% right.'
