Why Do You Write?

In an interview in the current issue of Creative Screenwriting, Craig Titley, writer of The Lightening Thief said, "but at the end of the day, I write to learn more about myself."

I thought revealing that was very honest and generous. Learning more about yourself is certainly a byproduct of any creative work, but is not everyone's intention. I write in order to make sense of things.

Why do you write? Please let me know.
