Em          C         G     D Em
Why do you look so familiar?
          C                G                D  Em
I could swear that I have seen your face before
           C                     G  D Em
I think I like that you seem sincere
             C               G                    D
I think I'd like to get to know you a little bit more

Am7                           G/B
I think there's something more
C
Life's worth living for

Chorus:
G
Who knows what could happen
C
Do what you do just keep on laughing
G
One thing's true
                            C
There's always a brand new day

Am7                               G/B   C
I'm gonna live today like it's my last day

How do you always have an opinion?
And how do you always find the best way to compromise?
We don't need to have a reason
We don't need anything, we're just wasting time

I think there's something more
Life's worth living for

Chorus:
Who knows what could happen?
Do what you do, just keep on laughin'
One thing's true, there's always a brand new day
Who knows what could happen?
Do what you do, just keep on laughin'
One thing's true, there's always a brand new day
I'm gonna live today like it's my last day

G
Find yourself Cause I can't find you
Am7
Be yourself who are you?
Who are you?
G
Find yourself Cause I can't find you
Am7
Be yourself who are you?
Who are you?

Chorus:
Who knows what could happen?
Do what you do, just keep on laughin'
One thing's true, there's always a brand new day
So you go and make it happen
Do your best, just keep on laughin'
I'm telling you, there's always a brand new day
Who knows what could happen?
Do what you do, just keep on laughin'
One thing's true, there's always a brand new day
I'm gonna live today like it's my last day
