What does it mean to write?

What does it mean to you when someone says “to write?”

What does it mean to them when someone says they are a natural to writing, that they have an affinity for it? That it seeps into their bones like erotic desire?

What does it mean to me? Are they talking imagery? Action? Time shift? Character or viewpoint? What is this writing that others have flocked to like bees to honey, and me, like a moth to a flame?
