If you are looking for a way to get rich quick you might consider taking up scorpion farming as the venom they produce is the most expensive liquid in the world. If you can manage to produce a gallon of scorpion venom from your scorpion farm you could make millions of dollars as it’s currently valued at $39,000,000 per gallon. The venom is sought after for many uses, most of which have to do with medical research. I think this would be the perfect cash crop for The Most Optimistic Farmer Ever.
