October Novel Prep Challenge

Considering that my absolute favorite books are part of Series, I'm a huge fan of multiple-part stories spun across multiple books. I rarely Rarely read anything that isn't part of a Series.

Of course, this has me questioning myself now that I'm sitting down to write a book. If I *love* series, shouldn't I try to plan for a world setting that allows for a Series to be written about it? Am I writing too encompassing of a story that won't allow me to pick it back up and write more about the world once I finish this book?
