I have a degree in product design, like you and also do a cad job, but I am freelance so can earn well above the average salary, and when you get bored after 6 months – just move to another company, well you could do that before the recession now you just stay as long as you can… if wish I had done a different degree but don’t know what. After all no one ever said when I grow up I want to be a cad technician…
