Songfacts®:

• This song is about somebody weighed down by the skeletons in his closet. He finally decides to let it all go and move on.
• This was co-written by Aimee Mayo, who in 2000 was named BMI Songwriter of the Year. Her other songwriting credits include "Amazed" by Lonestar, "Helpless When She Smiles" by The Backstreet Boys and "Wheel Of The World" by Carrie Underwood.
• CMT News asked McGraw why he decided to make this song the title track of his album. He replied: "It just made sense. You start collecting baggage your whole life, and it starts building up and building up and building up, and you reach a point where you know you're not a kid anymore, but you don't know everything, either. And the only way to move forward is to kind of cut some things loose. That's kind of where everybody gets to at this point in their life, I think, and it sort of made sense for my record."
