This probably won't be all that helpful to you, because most people aren't willing to be as flexible as I am and have almost always been--but maybe it will help you to know that lots of people are in the same boat. Great job, supposedly everything you want, and after awhile--yawwwnnnnn...
What worked for me was freelancing. I know many want the security of a fulltime job with all the bennies, and I know that's also a good way to go--for some. I never had a problem with staying employed, and I had many, many offers to work full-time at some place that I turned down.
I just think that for some of us (perhaps not necessarily you), a new challenge keeps us going. Once you've gotten the hang of a job and most if not all of the ins and outs, there's not much excitement left--at least for me. Some people are fine with it.
So just a question to ponder: do you think that perhaps the paras ARE working, and that your OTC is trying to nudge you out of your comfortable, familiar niche and into something else? Maybe something that will give you that sense of learning something new? Not saying (at all) that's what you should do, but thought I'd throw that out there.
