Desk/Cubicle Careers?

I recently graduated from college with a degree in advertising but have strayed from my major (go figure). I've realized I like to do very routine, mundane, boring tasks in a cubicle. I'm currently doing data entry work and love it but will eventually need to make more money. What kind of careers could I look into with my background? I am very open to getting a certificate or going to night school to become qualified for any careers.

Yes, I know of a few. Drafter, designer, architectural designer, graphics artist, clerking jobs, accounting jobs, researcher. Maybe that will help you a little.
