So this is my first tab and I did it all by ear. I tried to make an easier version 
for people who can't do bar chords. It sounds right to me, but if I'm wrong feel 
free to (politely!) correct me. Enjoy! 

Capo on 1st (optional)

Verse 1:

Em                   D            C
I've never been the best at honesty

C         Em                 D            C
I've made more mistakes than I can even count

C                    Em        D      C
But things are gonna be so different now

C                  Em      D      C
You make me wanna turn it all around

C                   Em        D        C
I think of all the games that I have played

C                 Em     D         C
The unsuspecting people that I've hurt

C              Em      D         C
Deep inside I know I don't deserve

C                  Em      D       C
Another chance to finally make it work


Chorus:

C         G       D
But I'll try to never disappoint you

   Em     C
I'll try until I get it right

G
I've always been so reckless

D
All of my life

D       Em D C
But I'll try

     G
For you


Verse 2:

     Em                  D             C
I've been the best at letting people down

C           Em                D                C
I've never been the kind of person you could trust

C                   Em       D          C
But if you give me half a chance I'll show

C               Em     D       C
How much I can fix myself for you


Chorus:

C         G       D
And I'll try to never disappoint you

    Em     C
I'll try until I get it right

    G
I've always been so reckless

D
All of my life

        Em D C
But I'll try


Bridge:

Em                 D         C
This time I won't make up excuses

Em               D             C
Don't give up on me and I'll prove that

C      D
I can do this


Chorus:

    G        D
I'll try to never disappoint you

    Em      C
I'll try until I get it right

G
I've always been so reckless

D
All of my life

        Em D C
But I'll try

G           D
I'll try for you

     Em       C
I'll try for you

G
I've always been so reckless

D
All of my life

        Em D C -one strum-
But I'll try

   G -one strum-
For you
