PALM BEACH GARDENS, Fla. - The next time you think of using the word impossible, think instead of Brian Mast.
His life changed forever in 2010 while fighting in Afghanistan.
"I was a bomb technician by trade, and I found plenty of IEDs as we call them," he says. "One of them found me first, unfortunately, before I was able to disarm it."
Mast lost both legs and a finger, but It's a moment he'll never regret.
"There's not one day I would ever trade two legs and a finger for any one of my friends," he says.
Now, six years later, a day he'll never forget.
It's not the first time Brian his been on the course - he's caddied at the Honda Classic Pro-Am before.
Wednesday, he was the one taking the swings.
Appropriately enough, Mast was in a group with baseball legend Roger Clemens, who he says is an advocate for veterans.
"He's constantly out there supporting em, so I'm proud to be out there playing along side him because I know the work he does out there."
Mast supporting military members as well, inspiring them with each picture perfect swing.
"Whatever you want to do, it's still possible," he says. "It's up to you to go out there and try it."
A veteran proving that impossible is anything but.
"What happens to us matters about this much, compared to whatever it is we do in response to whatever happens to us," he says. "That's what really matters - what we do in response to the challenges that we face."
