Lyric discussion by liv4caligrl 

wow im pretty sure this song is about settling down with his wife juliet and how he wants to settle down now. the title refers to what you are thinking before you go into the big gamble of marriage...you only live once...you only get married once. the lines"Oh, I'll be waiting for you baby 'Cause I'm through Sit me down, shut me up I'll calm down And I'll get along with you"

they all refer to how he wants a woman to whip him into shape and start this new life with her. He has had a problem with alcohol in the past and he needed her to shut him up and sit him down and calm down .
