You may have heard of stock trading on Wall Street—but livestock trading, the business of buying and selling actual stock animals (cows, bulls, and horses) takes place a bit closer to home. Interestingly, a degree in finance will help you in both careers, whether you want to help Google sell its shares to investors, or help farmers sell their cattle to a neighboring farm. In any kind of career involving trading and selling, it takes strong math and computing skills to succeed. But if you're interested in working with animals as a trader, you need to have experience plus "book knowledge," especially in the world of large animals, auctions, and farms. If you come from this background already, becoming a trader might be a great way to take advantage of what you already know and turn it into a satisfying career.
