I'm Bored

I think I know what my problem is.
I'm bored.
Ok. Let me back up a minute here. I'm sitting here at work at 4:45 on the last work day before the holiday break. I realize that I've gotten just about zero done and this was one of my more productive days this week. I'm trying to figure out why.
Then it hit me.
I'm bored.
I was helping someone in service Wednesday with a few problems and I was enjoying it so much. There truly are days when I miss that job. I don't miss my boss mind you, but the job. It was always different. There was always something new to learn, something else to figure out and to fix.
Now, my biggest challenges are pinning down a customer to a training date, shuffling around the training materials a bit and trying to get information out of people that don't have any. Oh, don't forget navigating across the country through backed up airports and through unknown cities relying only on Mapquest. I can (and probably have) trained in my sleep. I've had very few negative comments about training, and most of those were things that were out of my control, such as functioning connection to their system, wrong people signed up for the course, that kind of thing. I can't control who the customer sends to the course or fix their networks.
I don't want to be bored with my job. I enjoy interacting with the customers and training. I still enjoy seeing that ah-ha! moment. I'm just not challenged any more.
And the few challenges that are left (modularizing the materials, getting clearance and $$ and someone to develop web based content, the Big Book of Knowledge) just don't interest me. They're not very hands on. They don't make me thing hard or challenge me to push my boundaries. They all feel like busy work. Admittedly, some of it is self-assigned busy work. I think that makes it worse. I mean, I totally came up with some of those things just so I'd have something to keep me occupied in the office. I hate when teachers and bosses do that, when I do it I really want to scream.
The sad part is I have no idea how to fix it.
I feel like I've specialized myself into a corner. I know a lot about a very specific product in a very specific segment of a very specific industry. I don't want to go to work for one of the competitors. First off, none of them are local and I really don't feel like moving right now. That and I'm kinda bored with the whole industry.
Not that I know everything about it, far from it. It's just that, well, I want out of air. I want out of the power industry. I want something that I can be challenged by on a regular basis and go home feeling like I've accomplished something. I don't even always come home from a training session feeling like I accomplished much. Some days I think you could use a video recording and be about as affective. (Or is that effective, I'm a science major and I still have problems with those two words! Affect is the action, effect is the result... hmm... not sure that helped any... OK, enough grammar!)
Now, you ask, what would my ideal job be.
I haven't a clue.
It needs to pay as much or more than I'm making now, preferably good benefits too.
It needs to challenge me on an intellectual basis, and, I'm not trying to brag, but that can be tough...
I'd love it to be science related in some way, shape or form. I know my degree is useless at this point because I haven't kept much of the knowledge in my head, but still, it's something I'm interested in.
Working with people would be a bonus. I'm shy and timid and hate social gatherings as a whole, but I enjoy interacting with people in a business fashion. (Yes, that's me, blatant contradictions...)
Anyone have any suggestions?

Oh well, it's almost 5 now and I can escape. Gak and I are going to the movies this evening. I'm looking forward to that. Jon, Becca and Abi all get in this evening. That reminds me, I need to call Abi and see what time she thinks she might be up tomorrow...
Peace to all and may you be challenged enough to keep it interesting without being frustrated.
