I enjoy the process of writing a great deal, so as long as I have an idea and a spit of time, I don't have to do much to feel inspired.
For me, time is a big issue. I am definitely an all-in concentrator, and I hate to be pulled away from a project in the middle. I do not enjoy writing a drib here and a drab there. So very often, if I can't see a sufficient space of time in which I might reasonably finish a project, I do not start it. This is an ongoing issue. I am hoping that publishing We Are Called to Rise will give me the freedom and the confidence to work somewhat less and write more.
