This is played throughout most of the song:

     C             Am              Em          G

E----0--0--0--0----0--0--0--0--------------------------------
B----1--1--1--1----1--1--1--1--------------------------------
G----0--0--0--0----2--2--2--2------0--0--0-----0---0--0--0---
D----2--2--2--2----2--2--2--2------2--2--2-----0---0--0--0---
A----3--3--3--3----0--0--0--0------2--2--2-----2---2--2--2---
E----------------------------------0--0--0--2--3---3--3--3---

Then this is played toward the end (Where she starts to repeat "You push and you pull it"):

     C               Bb+G (I don't know the actual name of this chord)

E----0--0--0--0------3--3--3--3---------------
B----1--1--1--1------3--3--3--3---------------
G----0--0--0--0------3--3--3--3---------------
D----2--2--2--2------3--3--3--3---------------
A----3--3--3--3------1--1--1--1---------------
E---------------------------------------------

                      
C       Am             Em    
  Mr. Nothing's got a lot
G                         C   Am   Em   G
  He's got a lot to say
C               Am              Em       
  He's good at being what he's not
G                  C   Am   Em   G   
  Gives nothing away
       C            Am     
Another day goes on by
Em        G                      C   Am   Em   G
  And he never speaks his heart
C                Am                  Em   
  He takes his chance with what he's got
     G                     C   Am   Em   G
It's too late now to stop

You push and you pull and struggle with the knot
It's tying you up while you're fadin'
You give and you take and take what you got
Round and round 'till it breaks and
You push and you pull and struggle with the knot
It's tying you up while you're fadin' into your lie

Mr. Nothing is late
He's running out of time
He questions whether chance or fate will ever show a sign
Looks to the sky above
For a glimpse of what it means
And never never never make
Make no sense to him

You push and you pull and struggle with the knot
It's tying you up while you're fadin'
You give and you take and take what you got
Round and round 'till it breaks and
You push and you pull and struggle with the knot
It's tying you up while you're fadin' into your lie

(The chords change here)
C   Bb+G

(Bb+G)           C         Bb+G
You push and you pull it

(repeats til the end)
