Well, growing up my dream job was to dedicate my life to drawing. I would still like to do that to an extent, but you can't make surviving wages off art, at least I can't. My living wage is 3 grand a month, taking care of my mom and our pets, being the only provider in the house. Even if it were just me I doubt I would make enough to pay bills without taking on other jobs. So my more practical dream job now is to be a Zoologist, studying animals at a zoo. Why a zoo? Because I realized I would rather shovel animal crap, clean cages, and work with wild animals than be confined to a desk, doing the same thing with the same paperwork, and being around people every day.
Really all I want is to become a hermit in the mountains, living off the grid and draw to my hearts content. Stuff like that doesn't happen unless you're rich, though.
