According to OK, the rocker noted that he was initially drawn to national service after he finished school because he wanted to escape dissatisfaction with his own life.
"We were actually painting houses in Oklahoma. We were sitting in a parking lot. I look and there was a thing to sign up for the military," he said.
Followill continued: "I was looking at it really hard and thinking I'm gonna do it. I was just fed up with where my life was going and thought I'm gonna sign up."
The singer further explained that an unexplainable calling to write songs dissuaded him from the military.
"And as God as my witness, it was like on [the film] Field of Dreams, 'If you build it, he will come'. Something said, 'Write a song'. That night I went home and said, 'Hey boys, I'm going back to Tennessee [to begin writing]'."
