Job Offer

I just got a great job offer. It's doing exactly what I want to be doing, marketing, and for an industry I'm more interested in--health, rather than television. It pays over 10K more than what I'm currently making so just having finished the MBA might pay off. Now I just have to decide if I really want to change right now. My job is such a piece of cake and totally flexible. You couldn't ask for more freedom at work and easy money. So, is it worth it? I have a lot of thinking to do.
