Being full of ideas is a great and yet dangerous thing.
The best writers are the intuitive ones, the ones that do not think too much when they write. I always get myself into trouble when I am thinking.
When I am in the story that I am writing, my instincts take over and the characters pretty much write the story by themselves.
Why is thinking so dangerous for creative people?
Well storytelling is mostly about going on an emotional journey and unfortunately often our thinking is calculated, which results in us manipulating and controlling our characters to achieve our own desired result.
In my opinion, a writer must first empty themselves of their own ambitions and schemes and simply allow the creative process to take over.
