"If you ain't the lead dog, the scenery never changes"

This quote by Lewis Grizzard is a funny take on the concept of being a leader. It suggests that if you are not the one in charge, you will constantly be following another person's lead and never get to experience anything new or different. The "lead dog" is typically seen as the one who sets the pace and instructions for the remainder of the pack, while the others just follow along. In this context, the "scenery" represents the chances and experiences in life. Therefore, Grizzard is suggesting that if you wish to genuinely experience new things and make a distinction, you should be the one leading the way.
