Urban wrote this in 2006 and it was one of two new tracks on his Greatest Hits package. The country star explained to AOL how this self-penned song was inspired by his marriage to Nicole Kidman: "It's interesting, because the song's hook is, 'I think I got it right this time.' And I'm certainly at a point now where there's no thinking involved! [laughs] There's a little more conviction than that. And I had that full conviction when I wrote it, but as a songwriter, there are choices made with words because they sing well. So, 'I know I got it right this time' just doesn't sing as well as 'I think I got it right this time.' But as the song has evolved and grown, our marriage has evolved a lot. So [on the new recording], at the very end there's an ad-libbed line that says, 'I mean, I know I do.' [laughs] Songs are interesting, because they're written at a certain time in a writer's life and they mean a certain thing, but often, the really magical ones develop deeper meaning. And this song has definitely grown to have a deeper meaning for me."
