When people envisage the life of a writer they probably picture somebody scratching away in their notebook in a draughty garret somewhere, but most importantly, by themselves!
Well, I work in a garret of sorts (our loft conversion - but there is a draught!) and I tap away at my laptop rather than wear out nib pens on a daily basis, and, yes, I'm there by myself. I spend hours at a time immersed in my own thoughts (an interesting place to visit, but you wouldn't want to live there) and then, when I've got something that I feel is worth showing to others, I send it to an editor.
From there on in, writing is anything but a solitary business, as Juliet McKenna explains over at the Solaris Books blog.
Another (vague) acquaintance of mine, Gav Thorpe (ex-Games Workshop games developer and now full-time freelance writer) also has this to say about why we choose to pursue such a (seemingly) lonely profession in the first place.
