An Idyllic Job

I would like a job where I got to learn and explain things. For example taking highly technical rules written in IRSese and explain them to ordinary people. Or all the stuff I know about history, politics, and science and put them into layman language. Or writing about it. I think I could be good, heck I might even be great, but what sort of job title would that be? Science writer? History Professor? Journalist? Distinguished talking head?
