He went on to talk about the importance of intelligence, which he equated to "being sexy": "The sexiest thing in the entire world is being really smart. And being thoughtful and being generous. Everything else is crap. I promise you. It's just crap that people try to sell to you to make you feel like less. So don't buy it. Be smart. Be thoughtful and be generous."

Steve Jobs also made his way into Kutcher's speech. The actor, who portrays the Apple co-founder in the upcoming movie "Jobs," said, "Steve Jobs said when you grow up you tend to get told that world is the way that it is."

Kutcher wrapped with: "Everything around us that we call life was made up of people that are no smarter than you. And you can build your own things and you can build your own life that other people can live in. So build a life, don't live one, find your opportunities and always be sexy."
