Am I complainypants or do I need a new job?

[Jags4186]

I've been working at the same place since I graduated college in 2008.  The company is expanding and growing.  I've been promoted. Given more responsibilities.  I like my coworkers.  I like my boss.  What's the problem? 

I hate the work and I dread going in every day.  My job performance is suffering.

I have neglected looking because I have it in my head I can't make as much elsewhere.  Partly that's because I stumbled into my job and never really had to look before and partly because I would like to leave sales and that would mean probably taking a step back.  Advice?

That cycle isn't going to last. On the positive side, if you are good at sales you stand a better chance at your own business.

I'd suggest starting to look for other jobs, keep your ear out for other opportunities, that kind of thing.

askamanager.org has a lot of useful info about job hunting (and you'll also find you're not alone in not knowing whether to move to another job or not). Highly recommend reading her blog.
