This is Switchfoot's This is Your Life guitar tab.  I think it's right.

The low E string is dropped to a C# tuning.

G-------------------------1----
D--------2-------2-------------
A--4---4---4---4----4-0-4---2--
C#---0-------0----------------- Repeat through the verse.  I believe this is played by a keyboard or the bass.

Verse:
C#m                                      A B
Yesterday is a wrinkle on your forehead

Just listen and the verse follows the same chord pattern until the don't close your eyes part.

E                Eb/B  B                A
Don't close your eyes, don't close your eyes.
             E             B                A
This is your life, are you who you wanna be?  Follow same pattern throughout the chorus, until it goes back into the verse.  On the you've got everything to LOSE, hit a C#m to go back into the verse on LOSE.

The little riff you hear right at the beginning of the verse I think is played on piano, would be played on guitar like this:

E-12-11-9-----12-11-9-----------
B---------10----------10---9-7--

Now for the bass on the chorus, I believe the riff goes like this:

G------------------------
D-------2-----6----------
A---2-4---4-4---4-7-9----
E-0-------------------0--  At the next open E, repeat the bassline.

The little keyboart riff/solo/repeat thingy would go like this on guitar:

E-----4-----5-4----
B---2-----2-----4--
G-4-----4---------- And Repeat
