I can’t speak for other authors – I write because I love to write, but that doesn’t mean that people will want to read what I’ve written. So that leaves an interesting puzzle on the table. Write because I love to write, but create a story people want to read.
I started my career as an author writing action stories because, as a kid, I loved The Bourne Identity. In fact I loved it so much I read it all through high school. I mean it – I started in grade 8, and I finished it in grade 12. Needless to say, reading wasn’t my favorite hobby and I didn’t read very fast either. But once I read the book (finally, after 5 years), I knew I wanted to be an author and write my own stories.
