Before it's gone

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
