I don't need anything to help me concentrate except lots of quiet and no interruptions.
In a word, TRIVIA.
Silence and darkness, two essential things I feel a writer needs to really think. Thirdly, if you want to bring your true self out of your inner cave, I'd advise acting like a bear. I'm talking about getting lots of sleep, preferably for months at a time.
My work area is in my office/library.
I do best either late at night or early morning when I'm totally alone. Various pictures, such as a book cover, might inspire me.
Nothing. I use my computer and then I blank out the outside world and all noises and the subject on the screen is all I know and see.
chaos minus people
Nothing interesting. It's a typical work area with a couple of drawings from my daughter.
Background noise like music or something.
Exactly the opposite of what you would expect...I cannot write in a quiet room in the house. Not that I don't on some occasions, but my most productive time is at the local coffee shop with it's constant interruptions and all the hub-bub. I zone out when I need to and then chit-chat or observe others when I'm not concentrating on the next line. It may take me a little longer to write my one page, but I do enjoy getting there better.
Soft light, white noise, alcohol and tobacco in moderation.
I have no ritual objects. If it's reasonably quiet, free of distractions, that's good enough.
A comfy chair. A highlighter. Paper in the printer (just in case) and a beverage. I would like to say peace and quiet, but that just doesn't work for me. I like to hear a little background noise, it keeps me in the moment. If I had utter peace and quiet I might completely get lost in my work and forget to feed my family!
I just need to be comfortable. Nothing special. Luckily for me I can write anywhere - office, at home, play ground, loud music etc. Once I begin writing, my immediate environment does not count because I am totally absorbed in the environment I am writing. But atimes my physical environment makes me think and be creative. I dont like writing in a quiet place because I get distracted by the slightest interruption.
