I was well over qualified for my last job, but I preferred being happy rather than receiving a larger income.

Maybe have a think about "doing your own thing" - like turning your hobby into a business. From personal experience, I'm kicking myself because I didn't do it myself 10 years ago. From what I've seen, you are very creative and intelligent. Work for yourself, not a boss. Take it from me, you will never look back. The first step is always the hardest.

Something to think about, anyway.
