Remember how you were always going to do this when you were a kid? What happened? You really dropped the ball on that, didn't you? That's terrible. And then off you go to tell young children to live their dreams, to set their minds to something and accomplish it? You hypocrite. Go hang your head in shame.
Alright, I'm sorry. I didn't mean that. Your desires and dreams have changed, haven't they. Of course, how stupid of me. Give us a hug? Yes, there, isn't that better? Yes I forgive you. Okay. Okay. Okay. Okay. Okay let go now please.
But wouldn't you still like to go hunt for treasure? (The correct answer is "yes please".) Then you should shop at Deseret Industries. Today I found two small canvas paintings, a red cardigan, and a cool ceramic mug (I like ceramic mugs). In the past, I have found a brass menorah, a violin, a Hohner melodica, lotsa pants, lotsa shirts, some shoes, a leather jacket (which increases my badass-ity by 40%!), a crockpot, and, wow, a ton of other stuff. Garage sales work too.
Or, if you prefer buried treasure that you dig up with a shovel, there's geocaching.
