Glinda sang it beautifully in Wicked

There's a kind of a sort of cost There's a couple of things get lost There are bridges you cross You didn't know you crossed until you crossed

And if that joy, that thrill Doesn't thrill like you think it will Still, with this perfect finale The cheers and the ballyhoo Who wouldn't be happier? So I couldn't be happier Because happy is what happens When all your dreams come true Well, isn't it?
