When I write I always turn off my Internet to stop me getting distracted, and I have to have absolute silence when I'm writing or I can't come up with ideas. Another habit of mine is that I write on book-sized document pages in Word (rather than A4) so that it looks as though I've written a lot in a short space of time.
Where fonts are concerned I'm weird. Depending on the genre I use different fonts - sans serif for sci-fi and book-style font for fantasy. Also, I find I can overcome writer's block simply through a change of fonts, which is kind of strange.
I also tend to write from the moment I get up to the moment I go to bed, if I'm on a roll. I get absorbed in my fantasy world and it's very difficult for me to break out of it.
