Nothing is the same

When I was feeling 'bout sixteen, I never had no idea. Listen to me if you want to know what I mean, your expression will let me see. I never knew what I was looking for, I never had the time. And now that time has opened up my door, now I'm looking forward just to see what, just what's mine. When I was feeling 'bout eighteen, it's then when I began to see. No matter how hard you push on the door, it won't open without the key. Opportunity only knocks once, if you shut it out it's a sin. And when something keeps right on poundin', then, my friend, you'd better let it in. Now I feel just a little bit old and, sadness fills my brain. I can flash to future years and nothing is the same. Nothing is the same. Nothing is the same. Nothing is the same.
