I'm a finance person and I really love to see a creative person understanding the calculations of income. There are so many artists who don't even cover their expenses simply because they don't understand what you've just described here. I hope that many of them will read it and start thinking about it. I hate to see creative people struggling with money. It's the best to spend some time and understand the matter then have regrets later :) Or simply higher an accountant :)

Thank you for sharing and congratulations on your curie vote!
