That's what I keep asking myself.

What have I got? Really? Some money in my pocket, some nice threads, fancy car at my disposal, and I'm single. Yeah... unattached, free as a bird... I don't depend on nobody and nobody depends on me... My life's my own. But I don't have peace of mind. And if you don't have that, you've got nothing. So... what's the answer? That's what I keep asking myself. What's it all about? You know what I mean?
