Authors are often asked this question, and I have yet to form a conclusive answer.
To put it simply: Compulsion.
There are universes constantly exploding inside of my brain, vibrant worlds pushing against my bones and demanding release. Scenes play out on loop in my head, characters live and breathe through my eyes. They must be heard, they must be sculpted into something tangible.
Conversations of people both named and unnamed echo within my imagination. They evoke feelings that I have difficulties expressing to others. I want to share them with my readers, help them see what I see. And maybe get a glimmer of insight as to who I am.
There may not be meaning in the words I form, not conscious meaning anyway. I write what comes out. And it builds and builds. Sticky webs of interaction and intrigue. Relationships form and tear apart. The universe shifts as generations pass, forming new order for those yet to come.
I like to imagine myself as a keeper of lore, akin to the story tellers of the past who entertained with the tales preserved through eons. Each time a legend is spoken, something changes, a small detail that shifts the perspective of the future.
Everyday I sift through my vast collection of scraps and half-plots, wondering when I will have the chance to give them all the attention they demand. Perhaps one day, the well of inspiration will dry up, and my racing fingers can stop the toil. But that day is far out of my reach.
