Here’s how the math works. You need to meet two criteria. First, you have to create enough each year that you can earn, on average, $100 profit from each true fan. That is easier to do in some arts and businesses than others, but it is a good creative challenge in every area because it is always easier and better to give your existing customers more, than it is to find new fans.
Second, you must have a direct relationship with your fans. That is, they must pay you directly. You get to keep all of their support, unlike the small percent of their fees you might get from a music label, publisher, studio, retailer, or other intermediate. If you keep the full $100 of each true fan, then you need only 1,000 of them to earn $100,000 per year. That’s a living for most folks.
A thousand customers is a whole lot more feasible to aim for than a million fans. Millions of paying fans is not a realistic goal to shoot for, especially when you are starting out. But a thousand fans is doable. You might even be able to remember a thousand names. If you added one new true fan per day, it’d only take a few years to gain a thousand.
