Sorry if any lyrics or chords are wrong. 
There are a few parts I'm not sure of, so please feel free to correct me :)

Intro:
G    D    Em    C

   G                             D 
If time can turn in to day & we left too many things to say
    Em                                 C         
If we could turn it back what would we want to change
G                                     D
Now's the time to take a chance, come on we gotta make a stand
          Em                             C             Am
What have we got to lose, the choice is in our hands

                   D         Am            D     
And we can find a way to do anything if we try to

CHORUS:
G                 D      Em    
Live like there's no tomorrow
C                                                         
('Cause all we have is here right now)
G              D           Em     
Love like it's all that we know
C                                             
(The only dream I ever found)
G                           D  
Believe in what we feel inside
                        Em  
Believe & it will never die
                    C                    
Don't ever let this life pass us by
G                 D     Em        C
Live like there's no tomorrow

   G                                D                                      
If there never was a night or day & memories could fade away
      Em                              C                       
Then there'd be nothing left but the dreams we made
       G                                   D    
Take a leap of faith & hope you fly, feel what it's like to be alive
        Em                           C                Am
Give it all that we've got & lay it all on the line

                   D         Am            D     
And we can find a way to do anything if we try to

CHORUS:
G                 D      Em    
Live like there's no tomorrow
C                                                         
('Cause all we have is here right now)
G              D           Em     
Love like it's all that we know
C                                             
(The only dream I ever found)
G                           D  
Believe in what we feel inside
                        Em  
Believe & it will never die
                    C                    
Don't ever let this life pass us by
G                 D     Em        C
Live like there's no tomorrow

Am             C                     G   
Be here by my side, we'll do this together
     D              
Just you and me
Am               
Nothing is impossible, nothing is impossible

G    D    Em    C

CHORUS:
G                 D      Em    
Live like there's no tomorrow
C                                                         
('Cause all we have is here right now)
G              D           Em     
Love like it's all that we know
C                                             
(The only dream I ever found)
G                           D  
Believe in what we feel inside
                        Em  
Believe & it will never die
                    C                    
Don't ever let this life pass us by
G                 D     Em        C
Live like there's no tomorrow

You can play the Chorus once more and "fade out" but I usually just end with (G)
