Intro and Verse riff (The timing is tricky, so listen to it) 
G|-10h11-11-11-11-11-11-11-10h11-11-11-10h11-11-11----
D|--9-----9--9--9--9--9--9--9-----9--9--9-----9--9----
A|----------------------------------------------------
E|---------------------------------------------------- 
Continued: 
G|---7-7---7-7---7---7---7---7---7--------|
D|-5-----5-----5---5---5---5---5----------|
A|----------------------------------------|
E|----------------------------------------| 

Play that riff 4 times for the Intro and then another 4 when the vocals 
come in. 

Hook "If only you could see the you..." 
G|-----------------------------------------------------------------|
D|-2>--------------2>--------------2>--------------2>--------------|
A|---------3>--------------3>--------------3>--------------3>------|
E|-----------------------------------------------------------------| 

Then play the verse riff 4 more times, then the hook. 

Chorus "I'm growing up..." 
G|-------------------------------------------------------------------|
D|-------------------------------------------------------------------|
A|-------------------3>--------------------------------3>------------|
E|--3>-------5>----------------------3>-------5>---------------------| 

play that twice with the lyrics, then another 2 while the guitar impresses you. 

Then play the verse riff until the end, which is like another minute or two. 

Then the drums will cut out, which is a sign the song is almost over, you'll 
finish up the riff you're on, and then end the song with this: 
G|--10h11-10----------------------|
D|---9-----9----------------------|
A|--------------------------------|
E|--------------------------------| 

This is a really good song.
