As a full time dad trying to be a real comic artist, with family that don't look at art favorably I def know where you're coming from.

What helps me is a couple things. First is spite. When people say I can't or shouldn't do something, there's a voice in me heart that says "well now I'm gonna do it even more. How bout that asshole?"

And then second I don't really think I just draw. I look at some show or a comic book or manga volume I have and think of how cool it looks or cute and then I think it would be really cool if I could draw things like that, and I just do it. Even if it's a small sketch on a napkin corner.

And I think about my kid and how if they ask me what I do for a living or something like that how disappointed I would be in myself if I told her daddy settles for an office job, and how proud she might be in me if she says daddy followed his dreams and became an artist professionally (idk if that's something she'd really say but it's something I think about)
