I don't quite agree with not turning a hobby into a business. Countless people have success doing so and the same can hold true for this hobby. IMO, the key is to not treat the business as an extension of the hobby but, as a business. And, business is work, long hours, and at times, drudgery and worry. When it's time for work; Work. As with everyone else, hobbies are for leisure time so, save the hobby for when the work is finished for the day.
