Every writer is different. I'm a full-on control freak plotter, but that doesn't mean excellence isn't possible via other methods. I think it also depends on the kind of stories you are trying to tell. In my case, many of my stories are gothic horror/thriller mysteries, and therefore require a careful balancing act that means I have to have an ending first and work backwards from that point. I simply couldn't write novels like Spectre of Springwell Forest, Phantom Audition, The Irresistible Summons, and so forth without plotting out every detail, character profile, character arc, and so on.

For me, the drive to write comes from the voices in my head. Once I have that all-important ending, knowing that it has blown me away (I won't begin a story without that point), I cannot stop. The voices in my head are only silenced by being put on paper. I don't really have a choice. Sometimes it is a grind. Rarely does it feel like "inspiration" but just a lot of hard work. But I do believe forcing the issue helps. Writing 1,000 words of the novel/novella/short story per day, come what may, first thing in the day, before social media, writing articles, or anything else has become an ingrained habit.

That isn't to say I don't take breaks or tell the voices in my head to form an orderly queue at times. I spend the whole of December every year writing no fiction whatsoever, for instance. And I take other shorter breaks throughout the year, to recharge. :)

Whatever method ends up working for you, I hope you find it. :)
