'DWTS' Noah Galloway Details Personal Battle After Losing Limbs in New Memoir

"Living With No Excuses" hits bookstores Tuesday.

— -- Noah Galloway has gone from the battlefield to the ballroom.

Galloway said it was the devastating attacks on Sept. 11, 2001, that made him decide to fight for the United States.

"I was in college and seeing the things that everyone in the world watched live on television, that was enough for me to drop out of school, join the military, to be part of the fight," Galloway said.

In December 2005, Galloway lost his arm and leg after his Humvee hit a roadside bomb. In his memoir, Galloway, a father of three, reveals how he persevered.

He added: "I did it [wrote the memoir] because when I was going through those struggles, I thought I was the only one. I was hiding it from everyone and I'm hoping that it will connect with somebody or someone that may know someone that is going through that and see those signs and be able to help them."
