How Would I Know

I was sure
 That you were what I'd waited for
 you were the ultimate goal
 I wouldn't be hungry anymore
 Had a toast
 With everyone to recognize
 Just how far I had come
 That's why it's such a surprise
 I wake up restless in the night
 Can't fall back asleep
 Something isn't right
 And then it hits
 How would I know if this was it?
 How would I know for sure
 What's been for sure in my world?
 Caught a show
 Down at the Rockwood last night
 Came away humming a tune
 Sat down at home, began to write
 And like a habit
 I never was able to kick
 You put me in a trance
 Everything suddenly clicked
 I'm with you for better or for worse
 Don't know if you're a gift
 Or if you're a curse
 After all
 How would I know if this was it?
 How would I know for sure?
 What's been for sure in my world?
 (Could've been everything)
 Now I could be wrong
 That could have been all
 That could've been all there'll be
 But if I don't play along
 It won't ever be clear to me
 No it won't ever be clear to me
 How would I know if this was it
 How would I know for sure
 How would I know if this was it
 How would I know for sure
 How would I know if this was it
 How would I know for sure
 What's been for sure
 I know
 I know
 I know
 I know
