Writing spaces are personal. They need to be a safe space to let your thoughts run free, a place without distractions so that you can get down to the writing.
But waiting for a perfect spot is just inviting writer's block. No space is sacred, no place completely quiet. Dogs or children or significant others will always be competing for your attention. So you just have to do the best you can with what you've got.
My space is a desk by the window. More than anything else, I need natural light to write by. Whether I'm at Panera or Starbucks or my office, I need to be outside or by the window. I used to try to write at the office on my lunch breaks but without natural light, I found that my brain just sort of shut down.
But my perfect space is at home. I have a plain Ikea desk, a dasKeyboard...which is an old-school mechanical switch keyboard. It makes serious clicking sounds when I type that say, "I AM A WRITER!!!" It's the kind of manly keyboard Hemingway would have used if he hadn't written all his stories in the blood of a freshly killed lion.
Usually one or both of my dogs is with me, and I'm almost always writing early in the morning before Matt is awake. I face the wall so as not to be tempted by all the books and toys in my room, and I use the Freedom App to turn off my internet while I work otherwise I get sucked into Wikipedia while researching some small thing. I also use WriteRoom at full screen so that when I'm writing, it's just me, the keyboard, and the words. No formatting, no Internet, no nothing.
Sometimes I need music, sometimes I need silence. Right now, I'm going through a period of silence. For FML, I blasted party music that I hated but that got me in the mood.
But I can work just about anywhere.
So, what's your writing space like?
