Cool! Well graphic design is anyway, I've seen graphics artists make some really amazing things, like the skins for this website? I don't exactly know what I want to do when I leave school, my dreams when I was younger were to be in the military/police but now I'm more interested in Aviation :)
Good on you for wanting to do early childhood, you have to be patient and kind to deal with young kids, I think I'd suck at that :P Like Arnold Schwarzenegger breaking down in Kindergarten Cop, THERE IS NO BATHROOM!
