The Creative Cycle

I began a work back in 2007. It was the first time I sat down and started typing a book and knew it had to be finished. I had started a couple of stories in high school and set them to the side, lacking the confidence to be an author, and again in college, I started a couple of books, getting only a chapter or two written before the hideous creature titled Lack of Confidence swallowed my dreams and caused me to give up. 
The work I started in 2007 was a work of fantasy. It was to be a series of four books. I wrote the first and second draft of the first book. After finishing that I wrote Plain Jane and had it published. I started on the second book in the fantasy series once I finished Plain Jane, but then I had a request to write a companion novel to Plain Jane, so I set the two or three chapters in The Called Ones to the side and wrote Pretty Boy. After completing it, I went back to the fantasy story that started it all for me and writing. I added a few more chapters in the second book before I had another story come to life in my head. Wildflowers was birthed, so I once again set The Called Ones to the side and typed away, giving birth to a beautiful and tragic love story. Then I went back to my fantasy series, adding more chapters. It was at this point that I realized the first book needed more, so I went back to the first book and added additional chapters, a lot of them! 
After completing that, I expected to go finish the second book, but a different book was being birthed. I wrote the first half of it while it flowed and went back to the second book in The Called Ones series. It was during this time that I felt led to write a book for ministry. My husband and I are ministers, and I write teachings for adults, teenagers, and children. 2014 was dedicated to BASIC Training. I did not write within the realm of fiction during the entire year, outside of a chapter here and a chapter there! And now I am back to having that creative flow that is needed to write fiction. I've been mulling over the world I created in the first book in my fantasy series, and I am anxious to reenter Halanea and discover where the Called Ones go from here!
I'm expecting a great creative year in 2015! It would be nice to finally complete the second book and maybe even the third one! In a way it is the series that caused me to get serious about writing as a career, so I wonder at times if having it always lurking off to the side needed a little more here and a little more there is meant to keep me writing. What do you think? Do you have a motivator in your life that keeps you going back to your love or your hobby?
