I write historical fiction for a living. I find a real thing in history and make a good plot around it.
Dang.. I wish I could be you. I like writing, or at least think I could be good at it, if I didn't have complete lack of self-esteem. Too scared to do it for a living. Anyway, how does it work, exactly?
Don't be so down on yourself. Think of a historical novel.  Like something set to the background of WWII.  It's writings like that.
That does sound like fun. I'd be scared I'd have a lack of motivation to do it enough to write a whole novel, and then to consistently write novels for a living, and have deadlines. What else do you think I might find interesting about it?>
It sounds strict but it is not.  Historical fiction can be writing for novels, theater, opera, cinema and even video games. 
Ahh.. I see. What's your favorite part about it? or what do you want people to know?
To do it well you just have to be very detailed to the historical time you are depicting in the piece. 
That makes sense. I could see why if you weren't, how that would make you not be very good at that job.
