In his book, On Writing, Stephen King said he once wrote in a laundry room with his typewriter on his knees.
So how's your writing space? How large is it? Do you have a desk? Comfy chair? Since we moved a few years ago my writing space isn't what it used to be. I think we all have our quirks of how and where we like to write. Aside from the basic tools of desk, computer, chair, pens, paper, etc., there are things I need to feel comfortable to writeI need my back to the wall. Weird quirk? Maybe but it's what I need to zone out. So I position the desk so I have a wall behind me. Not always easy depending on the layout of the room.
I need Poe. See that little guy there under the lamp? That's my Edgar Allan Poe action figure. He inspires.
A nice lamp. This one is pretty and the light it casts is soft. After staring at either the computer screen or that stark white page, a soft light is a blessing.
What next? Coffee? Usually. Wine? Occasionally.
Most important thing in your writing space we learn from Stephen King again. He sat in that laundry room because it had a door.
Go into your space, shut the door and write.
