Show business is just that- a business. As artists, we must think of ourselves as a business. Our craft is a product that we must market, promote and sell. Training and perfecting your craft is important, but it is also important to know how to conduct yourself as a business. If you're not sure how to turn your craft into a business, find a class or research literary sources that will help educate you and show you how to do just that because the biggest stars aren't necessarily the most talented. Either they themselves or someone on their team has a great business sense.
