It's easy looking back but hard to understand
How the years can go so fast and slip right through your hand
Changing times and changing dreams
Can't help but wonder where we'd be
If we knew then what we know now
We could have turned the world upside down
We were reckless, young and proud
We had the whole thing figured out
We never saw the writing on the wall
Even though we thought we knew it all
Oh my friend, if we knew then what we know now
We tried to touch the stars burned a million miles of ground
We always went to far and never would back down
Oh, life is a chance you take
And live and die by choices you make
If we knew then what we know now
We could have turned the world upside down
We were reckless, young and proud
We had the whole thing figured out
We never saw the writing on the wall
Even though we thought we knew it all
Oh my friend, if we knew then what we know now
Oh my friend, if we knew then what we know now
