Writing can sometimes require more than just a pencil and some paper. Like any other creative profession or hobby, it can start with the basics and then quickly snowball from there. Some never find the need for a lot of paraphernalia, others take comfort in being surrounded by vast amounts of equipment.
I suspect that most writers eventually settle into a rhythm for their work, using only certain tools, at certain times of day, in certain places. Always using this pen, only at this desk in the attic, etc. I haven’t quite gotten to that level of sophistication yet. Until I do, I’ve put together my own Writer’s Essentials Kit. These are the things I simply can’t write without, at least not for long periods of time.
Item #7: Research, research, research. Because nothing kills an historical novel quicker than a scene of Admiral Nelson consulting Queen Victoria through Facebook about a campaign strategy against Alexander The Great.
