Where I come from, you don't really talk about how much you're earning. Those things are private. My dad never told my mum how much he was earning. I'm certainly not going to tell the world. I'm doing well. ↗
Once I've got the first draft down on paper then I do five or six more drafts, the last two of which will be polishing drafts. The ones in between will flesh out the characters and maybe I'll check my research. ↗
I had been writing for about twelve years. I knew pretty well how you could find things out, but I had never been trained in an academic way how to go about the research. ↗
My next book is also set in the eighteenth century. It's about the Revolution, with the focus on the year 1776. It's about Washington and the army and the war. It's the nadir, the low point of the United States of America. ↗
My shorthand answer is that I try to write the kind of book that I would like to read. If I can make it clear and interesting and compelling to me, then I hope maybe it will be for the reader. ↗
