I start at the beginning and stop when I come to the end. I love series. A life doesn't fit comfortably between the covers of a single book in my opinion. I am a fan of trilogies. I work on multiple projects.
Computers are wonderful.
If you have an idea, a moment of inspiration, just open a new file, type in the basic, name it, and close it to return to where you were. I love technology. A new book with unknown characters is always a tedious process at the beginning. I have to meet and get to know those characters. They advance by stops and starts.
