Inspirational sharpshooter uses feet

STEPHENVILLE, Texas (CNN/WFAA) - A college student in Texas is pushing himself as far as he can go every day and inspiring others.

He's a sharpshooter who doesn't have the use of his arms.

Marcus Parks is not just kicking back when he pulls the chair off and takes off his socks. He's firing away -- with his feet.

"Did I hit a bullseye? I certainly aimed for one," said Parks.

Parks types, writes and eats with his feet.

Despite more than 20 medical procedures, his arms just aren't strong enough to accomplish life's basics.

"My arms originally started out turned backwards, and so they had to cut in places and to fuse the wrists in order to turn them around," he said.

The 20-year-old Tarleton State University student said his condition isn't a limitation, but rather a motivation.

"If people think you aren't worth something, prove them wrong," he said.

So through an outdoor adventure class, Parks challenged himself.

"It gets your adrenaline going," he said, while at the shooting range.

Turns out, his mindset was the biggest battle.

"I can't shake the feeling that it's just right there, and all that's stopping me from taking it is me," he said.

It's with that attitude he approaches each day, teaching friends and strangers a thing or two about life.

"It's a higher calling to do something important. To tell people who are handicapped -- and people who aren't handicapped -- that just because you have physical boundaries, it doesn't mean you can't do things," he said.

In a way, he said he hopes he sends a strong message that he is a person first and that his disability doesn't define him.
