Who thought that something that is skill intensive, time consuming and not profitable (for most of us) would be so soul crushing? Seriously, what's wrong with us? Art is really hard and we still insist and diving deep into it. Energy management should be a mandatory course for comic artist. Depression is a serious problem among all of us.
Besides energy management, I think that the most difficult thing for me is writing. It seems easy enough, but is the most important thing in the comic. Your art can be the most amazing ever on the whole planet, but if the characters/story suck, you're out. People won't care and drop it after a few pages. Art is only good for the marketing, it makes people take it more seriously and enjoy it more. That realization just fires my anxiety when I'm writing. It makes me so judgemental of my own work that it HURTS to keep on.
Yeah, there's definetly something wrong with us.
