Big Heads - Reviewing Old Videos

I've been re- watching/listening to a lot of the Big Heads Videos on youtube whilst I draw. I've enjoyed it because it's encouraging to hear about what professional illustrators do/how they feel about jobs etc. I can relate to the bits I've already gone through, such as learning time management, and struggling with motivation sometimes. I think that sometimes it doesn't feel like a real thing that people do, but when I hear these videos, it's reassuring that people do actually earn a living this way, they just have to work really hard, which is what I'm prepared to do.
