this Crain's article it is said that art is an entrepreneurial endeavor.
It really is! Unless you got a job teaching art or you're lucky enough to do a comic strip or compose illustrations you're largely on your own! If you want to go down like Picasso, Warhol, or anyone like that you would do best on your own!
Well that's the point here. If you're an artist you might want someone to teach you how to use your skills so that you can be successful in that world. Hopefully such artists won't be penniless for their lifetimes only to discover that when they die their art can only be discovered.
Perhaps this course can teach the next Shepard Fairey!
