I don't think he is wondering about the present. I think he is asking if you "are" where you "wanted" to be in the past...that is what the song is about, in my opinion, the contrast between your former thoughts about how your life would be and your former goals and preconceptions. If getting there, and achieving what you wanted to, made you happy, or you realized that happiness was in fact somewhere else. I think the song talks about coming to terms with that.
