I think I was born inspired. No, but seriously, I am always writing -- thinking of stories, running dialog, imagining situations and confrontations. If I am by myself, I am almost certainly writing or thinking of what I will soon be writing. I wake up wanting to write. I go to sleep thinking about what I will write the next day.
Finding the energy to carry out the inspiration is a different thing. For that, I need lots of raw, green juice. ;-)
