This question I’m sure comes up a lot for people to ask authors, and authors to answer.  “How did you write your book?”  I know with some authors, everything is sketched out beforehand, then elaborated and cleaned up as it is written.  Others, like me, tend to just start writing and the story goes where it will.  Both work.  Just because you can’t write like your favorite author should tell you something.  You’re not that person.  Write to tell a story your way.  It takes time and practice.  It’s worth it in the end.
