You Don't Know A Good Thing

You Don't Know A Good Thing
You don't know a good thing
When you see it, when it's right before you
You don't know a good thing
When you have it, so you'll lose it

I give all my time to you
Am I a fool? Who needs this?
But if I was down on you, what would you do?
If I don't bring a thing, so
You don't know a good thing
When you see it, when it's right before you
You don't know a good thing
When you have it, so you'll lose it
But if I found someone else
Who needed me and left you
I've been thinking 'bout myself and no one else
All I'm trying to say is
You don't know a good thing
When you see it, when it's right before you
You don't know a good thing
When you have it, so you'll lose it
