My office is a mess.
Coffee and "mood music" are the essentials to my writing environment. Every scene in a story has a certain mood or feeling to it and I try to listen to music that helps me feel what I'm writing a little more deeply. That helps the words come more easily for me to set the scene for the reader. Coffee is just a mainstay of my diet, and helps to keep my mind alert and active when I'm writing.
Just my imagination.
Music is something that I must have on when I am writing.
Silence and nice light.
I am surrounded by over a thousand books.
My work area is wherever I happen to be when either 1) inspiration hits or 2) I have ten minutes, a pen, and some paper.
I write if, and only if, there is no one else nearby. I like quiet when I write.
A comfortable chair and a cup of coffee are my writing partners. I'm old school. Yes, I use a laptop, but my first drafts are always written by hand.
I make sure to surround myself with good lighting, good music, and artwork from my favorite artists. When I'm writing, I'm a solo act. No friends, no conversation, no phone calls...just me and what I'm working on.
Interesting question. Positive statements hang on the wall around my writing space. I also have sweet smelling candles in my writing space and a good light.
Guns...I'm not joking.
Books...the internet...a comfortable chair (which could be improved) and quiet...
My desk is a mess. The clutter does not help me concentrate, but I can't seem to keep it tidy. My kids are constantly moving things around, but that's how I live. My writing and my family life are completely entangled, or perhaps enmeshed is the word. I don't try to separate, because trying only creates conflict and stress. My inclination is to isolate myself with my projects and work blissfully uninterrupted for days, but instead I write when I can throughout the day interspersed with mother work. I often work with a baby in my lap.
