Why we write.
I have written a number of stories, and have more still yet to write. Not expecting to become famous or rich, I write, as many others do, because its part of my nature just to want to tell these stories. As Ferris Jabr wrote in Harpers:
Stories sustain us: they open paths of clarity in the chaos of existence, maintain a record of human thought, and grant us the power to shape our perceptions of reality.
