Either Strum or play in the same pattern as the intro throughout, obviously 
without the strum at the end.
Either Standard Tuning or Capo on 1 if playing it like the intro
Also keep your 3rd and fourth finger on like this:
E----3---|
B----3---|
G--------|
D--------|
C--------|
E--------|
for everything except the chorus, but still keep it on the Em7 chord for the 
chorus, hope that made sense :)

Intro:
E-----------------------------------------------|
B-----------3-----------------3-----------3-----|
G--------0-----0-----------0-----0--------0-----|
D-----2-----------2-----2-----------2-----2-----|
C--3-----------------3-----------------3--3--3--|
E-----------------------------------------------|

Verse 1
C (x32010@1)              Em7 
I spent my time, watching
     G (320003@1)                            CThe (x32010@1)spaces that have grown between us.
                      Em7

       G (320003@1)                             C (x32010@1) 
Oh the scars that come with the greenness.

Now walking back, down this mountain,
    G (320003@1)                     C (x32010@1)   
The strength of a turnin' tide.
                            Em7
Oh the wind so soft, and my skin,
         G (320003@1)                  CYeah (x32010@1)the sun so hot upon my side.

All I was searchin' for... was me.

Oh oh-oh, all I was searchin' for was me.
