You obviously are the frustrated artist type, and that reflects both your greatness and inaptitude to just create for the fun of it.
Art is just not a good way to make a living, it is a way to become someone special and make people bow down to you. Nothing less, but nothing more. If you have the flame, you'll just do it for the heck of it. No matter how unrewarding it is. I'm pretty sure you have that flame, judging by how hard you tried to convince yourself of how you hated making RAB cartoons in your post.
I'm pretty sure you'll be back with more RAB once that depression of yours has ended, wich might not be too soon if you're reading this thread. Wait... it just got deleted. I'll post my reply here, then.
