If anyone makes it seem like living the life of an artist is easy it's probably because they've been shy to share all the sh*t they've gone through and continue to improve it in order to achieve their version success. I personally don't do anything of this creative endeavor full-time yet but I can tell you there's a lot of sacrifices involved which hasn't bother me because it still allows me to spend time with people I love while still being behind the camera when I'm not a work.
Someone who I've learned a lot from not just from his work but from his continuous writing on the creative life is Nick Onken. He said, " My journey...was NOT easy… however, I discovered a few tricks along the way that I know could make it a whole lot easier for YOU."
He recently wrote an article on this very topic which I highly recommend you sit and take notes on, especially for those considering starting a career in art.
