Stephen Sliver just released a video encouraging artists to stop wasting their time and energy by creating art for free. I love it.
Back in Colorado I struggled running my own company, I took on a lot of odd and end gigs but they were all paid. I always ran into individuals or organizations that wouldn't pay me industry standard wages or what I felt I was worth. And I would always walk away. I learned the hard way, and I learned very quickly. (except for my tv series project - but that's another story for another time.)
Anyways, watch the video, it's worth your time. Thanks Stephen.
