Goodreads asked Mark Justice:

What’s the best thing about being a writer?

Mark Justice Having the freedom to create worlds from mere imagination.
Seeing characters take on lives of their own beyond what you invent them to be. They start of as just a rough sketch, but in time, they become almost living entities. That's incredibly exciting, and at those times, the act of writing feels more like simply recording what these characters are saying on their own rather than through your invention.
When you find out that other people enjoy your work. That's immensely satisfying.
