I reach down deep.
Just when I thought I've mined it all, I discover hidden treasures within me: gold, diamonds, sapphires, emeralds, sundry rare stones.
Wow, I had these all along.
I thought I had nothing but trinkets but I've had millions of dollars of metaphorical treasures inside of me the whole time.
I'm rich. I'm metaphorically rich, which is almost as fun as being actually rich.
