Step 1: Buy, buy, buy! Collect as many Beanie Babies as possible. The more, the merrier.
Step 2: Store them in a safe, climate-controlled environment. You don't want your Patti the Platypus to get all soggy.
Step 3: Trade them with your friends and family. Who needs cash when you can have a Peso the Penguin?
Step 4: Sell your collection on eBay. Good luck with that.
Step 5: Declare bankruptcy and start over. Ah, the circle of life.
