Lyrics:

New Directions
Don't (don't) stop (stop)!
Don't (don't) stop (stop)!

Sam with Quinn
If you wake up and don't want to smile
If it takes just a little while
Open your eyes and look at the day
You'll see things in a different way

New Directions
Don't stop thinking about tomorrow
Don't stop, it'll soon be here
(It'll soon be here)
It'll be better than before
Yesterday's gone, yesterday's gone
Don't (don't) stop (stop)!
Don't (don't) stop (stop)!

Quinn with Sam
Why not think about times to come?
And not about how the things that you've done
If your life was bad to you
Just think what tomorrow will do

New Directions
Don't (don't) stop (stop) thinking about tomorrow
Don't (don't) stop (stop), it'll soon be here
(It'll soon be here)
It'll be better than before
Yesterday's gone, yesterday's gone

Ohhh, ohhh
(Finn: Don't stop, no!)
Don't (don't) stop (stop)!
(Finn: Thinking about tomorrow)
Don't (don't) stop (stop)!
(Finn: Ohhh, no, no, no)
Ohhh...

Finn
All I want is to see you smile
Quinn
If it takes just a little while
Finn
I know you don't believe that it's true
Rachel Finn
I never meant any harm to you
Ohhh...

New Directions
Don't (don't) stop (stop) thinking about tomorrow
Don't (don't) stop (stop), it'll soon be here
(It'll soon be here)
It'll be better than before
Yesterday's gone, yesterday's gone

Don't (don't) stop (stop) thinking about tomorrow
Don't (don't) stop (stop), it'll soon be here
(It'll soon be here)
It'll be better than before
Yesterday's gone, yesterday's gone

Oooh, don't you look back (Don't you look back)
Oooh, don't you look back (Don't you look, don't you look, no)
Yeah, yeah, yeah

Oooh, don't you look back
Don't you look back, don't you look back
Don't you look back, don't you look back

Oooh, don't you look back (Don't, don't, don't you look back)
Don't (don't) stop (stop) thinking about tomorrow!
