verse 1: 
Am 
I had a plan and it made God laugh 
C 
It didn't work, should've checked the math 
G 
I hit the wall 'cause I live too fast 
D 
I didn't know it could hurt that bad 
Am 
I took the hope but there was none 
C 
I should've known that was so dumb 
G 
(Woah oh oh oh) 
D 
(Woah oh oh oh) 

verse 2: 
(Same Chords) 
I was a dick when I was seventeen, 
I thought the world brought me everything 
But who am I knew I'd never be 
Is all the shit that happens in between 

G 
(Woah oh oh oh) 
D 
(Woah oh oh oh)

[Refrão]
E                G 
There's no going back, 
              D                        A 
When life's a loaded gun, you pull the trigger, trigger 
E                G 
There's no going back 
            D 
The past is in the past 
             A 
Thank God it doesn't last forever 
E 
There's no going back 
D 
Fuck that going back 
E 
There's no going back 
D 
Fuck that going back 

(Same as verse 1) 
Yesterday was another life 
Turning left didn't turn out right 
Stuck in hell when I was twenty-five 
You can't regret what you don't decide 
I should have stayed, should have let go 
Should've, could've means you'll never know 

(Woah oh oh oh) 
(Woah oh oh oh) 

(Chorus) 
There's no going back 
When life's a loaded gun, you pull the trigger, trigger 
There's no going back 
The past is in the past 
Thank God it doesn't last forever 
There's no going back 
Fuck that going back 
There's no going back 
Fuck that going back 

G 
The future I'm living now 
Am 
Is not what I'd thought it'd be 
Em 
The person I was before 
C 
Is nothing like me 
G 
The future I'm living now 
Am 
Is the way that I want it to be 
Em 
The minute I walk through the door 
C 
I slam it behind me 

(Chorus) 
There's no going back 
When life's a loaded gun, you pull the trigger, trigger 
There's no going back 
The past is in the past 
Thank God it doesn't last forever 

There's no going back 
Fuck that going back 
There's no going back 
Fuck that going back
