Cover art for Once In A Lifetime lyrics by Wolfsheim

I always understood it as him talking to his heart that basically "took" his wife and unborn son (I guess he wants a son) not in a literal way but in the way that his fear of connection and all that comes with it always stops him in his tracks and it ruined countless opportunities and potential relationships and now he may see another chance coming up (possibly the last realistic chance because he is older now) and his heart is starting to pound in fear again but this time he's not having it.
