Georgia Tech sophomore Nicholas Selby says he was surprised by the reaction to his convocation speech welcoming freshmen to the Atlanta university.
The video quickly went viral on the Internet (watch it below). It had more than 1.8 million views on YouTube by Friday morning.
Selby's inspirational message included theme music from "2001: A Space Odyssey." He tells his fellow students about his dream of building the Iron Man suit and says anything is possible.
"If you want to change the world, you're at Georgia Tech, you can do that," he tells the incoming freshmen. "If you want to build the Iron Man suit, you're in Georgia Tech, you can do that!"
Selby, who is from the Phoenix area, is part of the mechanical engineering class of 2015 at the Georgia Institute of Technology.
