I want to quit my job

I want to quit my job. I am dissatisfied with my work. I thought maybe if I have something outside of work that fulfills me, having a "pay the bills" job is fine. For about a year, it was. However, things for me have changed. I'm starting to feel irritated with/intolerant of things that never really bothered me before: my pay, my work hours, the way one or two people treat me, the trainings and meetings I'm  expected to attend, my new responsibilities, etc. In fact, sometimes I don't want to do anything and get annoyed when people ask me to complete various tasks. However, I keep my emotions in check and do what I need to do. I know it's not my work - it's me.

The truth is, I don't feel fulfilled with my work. I don't feel like I'm growing in the direction I want. When you are working toward a goal and you're on the path you want to be on, you can put up with all kinds of crap: people taking advantage of you, lousy hours, little to no benefits, and low pay. You deal with it, because in the end it will pay off. On the other hand, if you have everything - good pay, good benefits, flexible hours, great coworkers - but don't feel fulfilled, all these things get on your nerves...probably irrationally. That's where I am right now.

The problem is, I don't know where to go or what would make me feel fulfilled. I've been reading a lot of articles on fulfilling careers and career changes, but nothing has sparked an idea. Or a plausible idea. I just know I want to create things. I've thought about photography, writing, websites, and marketing/advertisement. I've also thought about become a dance teacher...but the pay for that quite low unless you're well-known or have serious business skills (aka not a great teacher, but you can sell).

I don't know what I'm going to do, but I want to figure it out soon. I'm increasingly dreading the days I have to go to work and I'm getting cranky. I need to figure things out before I explode.
