What's the biggest difference between you now, at age 31, and Eric Church at 21?

Everything! I was pretty reckless at 21. I was in college, and I was out playing shows four to five nights a week, for no other reason than I was able to get free beer when I played. What's changed is my overall direction in life, goals, everything. I would say the kid at 21 couldn't be more different than the man at 31.
