I don’t think so. If you want to write hanging upside down from a lamppost with an Etch-a-sketch, you go right ahead. (If you do write hanging upside down from a lamppost with an Etch-a-sketch, please get someone to take a pic and post it on social media so I can see how it’s done.)
Some of us plot roughly, some plot minutely, some don’t plot at all and ‘write by the seat of their pants’, therefore winning themselves the title of ‘pantsers’. I make use of notes, timelines and mind maps and others say this would drive them demented.
I like to write in silence. This, in the not too distant future, is going to earn me an office at the bottom of the garden so my silence doesn’t disturb anyone else’s noise. If I don’t have silence I play music. Sometimes it’s classical but I also have an ever-growing and eclectic writing playlist consisting of Pink Floyd, Damien Rice, Jimmy Nail, Neil Young, Rod Stewart, Billy Joel, Eddie Vedder, David Bowie, Mark Knopfler, Leonard Cohen, Harry Nilsson, Carole Bayer Sager and Cat Stevens. It’s what I think of as ‘in the zone’ music and I have an almost Pavlovian response to hearing it … it’s time to work. My friend Elizabeth Chadwick writes with heavy metal music playing and constructs a different playlist for every book. Some people write in cafés or at work during lunch, with the children running laps of the kitchen or while the TV’s on at night. Some say silence would agitate them.
I think you should write in the way that’s right for you – but I do suggest that you try other ways from time to time. You never know when something’s going to work. And if it doesn’t – then you never have to do it again.
