I get what you're saying. It's difficult to convey this to some people. I've been through a lot of jobs in quite a few different fields over the decades and have the appearance of being restless if I am not careful about how I craft my resume.

I've been asked "okay, but what do you _like_ to do?" which just puts me in a position to have to explain that I have a passion for learning new things and experimentation, but nobody is going to pay me to read books and play around in a workshop all day, since those jobs are few and definitely already filled.

So, it's a hobby, instead.
