Your art is not good enough to make a living from it.
That statement is probably true for a lot of people, but first we need to explore what we mean by "not good enough."
Not good enough could mean redundant. If there are 11 dance companies in town that focus on ballet and you pop up as #12, there just may not be enough room in the market for you.
Not good enough could mean you're targeting the wrong audience. It could be the greatest art in the world, but if the audience isn't the right fit, you have problems.
Not good enough could mean you're targeting the RIGHT audience, but it's just too small for you (and your team) to make a living from it.
Not good enough could mean your expectations were too high to begin with.
And of course not good enough could just mean plain ol' not good enough. The bar to make a living from art in a cluttered, competitive world is INCREDIBLY high. You've got to have superior quality, authentic marketing, a committed following and more then a little luck.
But I think the good news is that all these issues have solutions. You can target a different audience. You can invest more time, energy and focus into your art. You can avoid doing what everyone else is doing.
Not good enough can become more then good enough.
