What's useful about the post for indie musicians is BZTAT talks about today's artists (I would include musicians in that category), "...must be creative entrepreneurs engaged in the world of business..."
Essentially, she's talking about when you're actually engaged in making your craft your living the romantic notions most associate with being a passionate artist are not what it's all about. In fact, most artists/musicians that make a living from their craft find that they work harder and longer hours than they ever did at a day job. However, the difference is that passion drives the efforts making it a labor of love.
Nonetheless, anyone who is a professional artist/musician (being paid for the artistic services you provide), whether part-time or full-time, must know that being a professional in one's passionate/craft is to be in business. The sooner you realize that and embrace your entrepreneurial spirit you'll find your creativity, for both your craft and the business of your craft, will take on a whole new dimension. You'll end up giving yourself an advantage by learning and excelling at the business side of your craft simply because much of your competition won't.
