This is hands down the best article I have read on photography as a business.

I particularly enjoyed your observations on how photographers and artists don’t like, or don’t want to market their business. At the exhibition of an artist friend, he tried to tell me he wasn’t bothered about sales, when he blatantly was. Some people think it is uncool to admit they want to actually sell their work, even though to my mind, this is the greatest compliment anyone can pay your work.
