I see it a lot. Writers stating that they write because it's fun, because it's entertaining. This is something I probably spend way too much time thinking about. Because I don't find anything about writing fun. For me, writing is hard. It's really fucking hard, and it gets harder the older I become.
I don't find one single aspect of the writing process enjoyable, on any level. When I write, I'm poking at recent wounds, opening up old scar tissue, raking around in the wet meat to find the core of the story. It's emotionally, physically and spiritually draining. I honestly can't see what could ever be fun about it.
But I envy those writers who say they have fun when they write. I wish I could be that way. I'd probably write more; I'd certainly feel more love for the process. I might even be less of a miserable bastard. Maybe.
The only thing about writing that gives me any ounce of pleasure is having written. When I finish something - be it a short story, a novella or a novel - I feel good, about myself and about the world. That good feeling is fleeting; it lasts only as long as it takes for the realisation to hit me that I have to start all over again on another story. But at least I have it, and it's mine. All mine.
I think that's the main reason I put myself through the emotional shitstorm of writing: to have written. Because having written is so much better than not having written.
