From hardware tech to helpdesk

I just recently took a job as a contractor for Sprint, working on their helpdesk. I’ve only been their a week, but I’ve pretty much figured out this is NOT what I want to do. I’m going thru a training program right now, but I’m finding it hard to concentrate, vecause I know I don’t want to be there. I guess my question is, what do you do when you take a new job, and find out it’s not what your looking for?
