"Life on the road can get a little one-dimensional. I didn't want to reach 40 and have to say all I'd done was look out the window of a tour bus and get drunk"

This quote by Bruce Dickinson talks to the concept of living a life of purpose and meaning. He is recommending that life on the road can end up being ordinary and recurring, and that if one does not put in the time to check out and experience life, they may reach a point in life where they have nothing to reveal for it. He is cautioning against living a life of excess and recklessness, and rather motivates individuals to put in the time to check out and experience life. He is suggesting that if one does not take the time to do this, they may reach a point in life where they have nothing to show for it. He is motivating people to take advantage of their lives and to put in the time to check out and experience the world around them. By doing this, they can make sure that they have something to show for their life when they reach 40.
