Kutcher first addressed the teen audience by revealing some secrets about his life -- he changed his name when he was 19, the moment he began acting. According to Kutcher, actors need those secrets to keep their careers going.
"I feel like a fraud," said the 35-year-old "Jobs" star. "My name is actually not even Ashton -- Ashton is my middle name. My first name is Chris."
The actor continued by explaining three life lessons he learned back when he was Chris: Opportunity, being sexy and living life.
"I believe Opportunity looks a lot like hard work," said Kutcher. "I never had a job in my life that I was better then. I was always just lucky to have a job."
And then there's being sexy. But if you think being sexy is about striving to look like the hottest celebrity in Hollywood, according to Kutcher, you're wrong.
"The sexiest thing in the entire world is being really smart. And being thoughtful. And being generous," Kutcher explained to the crowd. "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."
Before closing his speech, Kutcher shared a message originally given by the late Steve Jobs:
"Everything around us that we call life is made up by people that are no smarter than you. So build a life. Don't live one -- build one."
Those are some encouraging words given by the once rambunctious "That '70s Show" actor. If the teen crowd can retain a fraction of that information, there's hope for the future.
