Remember when you were seventeen   You's goin' crazy, you know what I mean   It wasn't that long ago in the grand scheme of things   It wasn't that long ago, you think you're so much smarter now      Twenty one, everything stays in place   Forty one, somethings start to fade   Well, when you're so young you wanna be older   And when you're older you want the body you have now      I believe in a perfect world   You rule your own universe   The only gun you'd ever need will be in your brain   The only gun you'd ever need is in your hand      You want this now you want that   Can't have it all, you should enjoy what you have   But I know what you want, well I know what you want   Well I know what you want, you want the better of two halves   Well I know what you want, well I know what you want   Well I know what you want, you want the better of two halves
