Goodreads asked Merry Jones:

What’s the best thing about being a writer?

Merry Jones Well, the best thing about it for me is that it keeps me sane. If I don't write, I get anxious, depressed, irritable. It's as if energy is building up inside and needs to be released. And writing is what releases it.
Other than that, writing lets me work my own hours, at home. I have no boss (although agents and editors can feel like bosses). I can wear what I want, usually pj's, without makeup or even showering.
Best of all, when a book is finished, I send it off to find its readers. For me, that's what writing is all about--Without readers, what's the point?
