You'll find this song on the album 'Crush' released in 2000. Jon wrote it for his daughter Stephanie (*1993) and already performed it twice with her on stage. There are lines like: 'The quuen of
hearts will always be a five year old princes to me' or 'I got the girl, she's a work of art' which show how proud Jon is of his daughter. She means a lot to him and this is his way to show it.
Another aspect is - as always - the typical optimism of the band as shown in lines like: 'And when this wicked world starts brining me down I tell myself that I'm one lucky guy, I got the girl'.
Jon presents Stephanie as a main motivation for him to get up every day and be motivated and positiv.
-> To sum this up we can say that this is one of the songs with a big autobiographic part.
