Generally, what motivates you to write? Fame, passion?

It’s purely a passionate desire to do what I am best suited to do. When I go into that space of creative writing, even in my sleep, scenes for the novel keep developing. At such a moment, I would reach for my iPad to take notes and release those scenes from my thought process, else sleep would remain elusive.
I am thankful to God for the grace He has given, and dedicate myself to His steer.
