I've got a great new idea that's going to make me a ton of money! I'm going to make a Catholic Catechism alphabet coloring book! I checked around and didn't find any others so I've got the market all to myself. With something like a billion Catholics in the world, if I even get a small percentage of them to buy my book, I'll be rich as Rockefeller!
It can't miss! I've already started picking out the mansion I'll buy with my insane profits.
