( Am F C G ) X2

[Verse]
          Am         F 
When I was a young boy
 C                       
I was living for the moment
G
The world was wide open
     Am      F
I had every choice
C
But with so many choices
  G
I just didn't know what to do now
 Am               F
All I say is just forget it
                C
If you tell me I'll regret it Just let it be what it is
G
Coz it's so easy to say
 C         F              Am
If I knew yesterday what I know today
G
Where would I be tomorrow
C               F
I won't let my soul slide away
       Am
I'd do whatever it takes
                     G    
Coz this time's only borrowed
      F          C         G
I got one life, one life, one life
 Am
And I'm gonna live it
      F         C         G
I got one life, one life, one life
 Am
And I'm gonna live it right
          Am        F
My daddy sat me down
         C                                G
He said "Son, it's probably time to start making some plans"
           Am             F
And I said "No, not right now"
     C
With so many choices
 G
I just didn't know what to do now
  Am                     F
All I say is just forget it
                     C
If you tell me I'll regret it
                        G
Just let it be what it is Coz it's so easy to say
 C         F               Am       
If I knew yesterday what I know today
              G
Where would I be tomorrow
C              F
I won't let my soul slide away
    Am
I'd do whatever it takes
                      G
Coz this time's only borrowed
      F         C         G  
I got one life, one life, one life
 Am
And I'm gonna live it
      F         C         G
I got one life, one life, one life
 Am
And I'm gonna live it right

        F*           Em*
You say the more you think
    Dm*             C*
You know what's right
   F*        Em*
The less you do
         Dm*        C*
What you feel inside
     F*    Em*            Dm*      C*      
So I won't pretend that I always know
       F*        Em*    Dm*         C*
I just follow my heart wherever it goes
      F*       Em*     Dm*     C*
And I may not always get it right
    -x68866-               Dm*
But at least I'm living coz I've only got this...

        ---------------------------------------------
     F        C         G
One life, one life, one life
 Am
I've got this one life
  C            F          Am
If I knew yesterday what I know today
  G
Where would I be tomorrow
  C                 F 
I won't let my soul slide away
       Am
I'd do whatever it takes
                        G
Coz this time's only borrowed
      F             C         G
I got one life, one life, one life
  Am
And I'm gonna live it
      F             C         G
I got one life, one life, one life
      Am
And I'm gonna live it right
         Am       F
When I'm an old man
             C 
Hope I'll be rocking in my chair
 G
Smiling to myself
            Am        F
I'll tell my baby girl
        C          
You only got one life
G                               C
So make sure you live it right
