Richie Parker was born in May 1983 with a condition known as Bilateral Amelia which left him with no arms.
He grew up with a chorus of doubters telling him what he couldn't do without hands - ride a bike, drive a car or find a good job. But Parker never listened, and today he holds a mechanical engineering degree, drives his own car and is a respected engineer for NASCAR's most winning organization, Hendrick Motorsports.
"I don't listen too much to people when they tell me I can't do something. There's not a whole lot that's gonna stand in my way," says the man who takes pleasure in solving engineering challenges.
"Every step of the way in life there have been people who say I can't do things. Said that I couldn't ride a bicycle, there have been people who said that I couldn't live on my own. Couldn't get a good job and support myself or I couldn't go to college and graduate," the inspiring engineer told ESPN.
In the meantime, though, the high-achieving engineer said he is always looking to achieve even more.
"I'm just never satisfied," said Richie. "It's what drives me. I don't know where it comes from. And sometimes it kinda drives me crazy but that's how I live my life."
