Before It's Gone lyrics

I don't get the difference? It couldn't get much lower Feeling so much older Than I used to feel Swimming in the rivers Walking on for miles If this could last forever Then I'd like it to... Seems to be this way If you could find an answer Look into tomorrow You didn't used to matter But things have changed Peering through the sunrise You used to look much better Colours are much denser Than they seem to me Leave it all behind Cleaning all what escaped your mind But the cracks won't close Until you want them to So be brave and take control of you If you could turn a corner Then I'd want you to keep going Head for the horizon Before it's gone Leave it all behind Cleaning all what escaped your mind But the cracks won't close Until you want them to So be brave and take control of you
