I once had the power cut off at my house while they... I dunno replaced the pole or something... anyway it was the first day of Nanowrimo so I took my laptop (bad battery, lasts approx 6 mins) to my aunt's and wrote 7000 words in 4 hours. There was no internet, no animals, no tv, no people because my aunt lives alone and had an appointment that took up most of the 4 hours - I'd never written 7000 in such a short time before, nor have I since. However I find it much easier because I knew there was no internet to distract myself with - at home I know it's there so I use it and I doubt unplugging it would work because I just bet I'd go "ooh better research that, better logon and go to google" and be distracted for the next hour.
Live simply, so you don't have to work a demanding day job.
No kids? Well, it does help a lot, but some of you have to reproduce to keep the species going, and good writers reproducing will keep up the intellect/imagination level in the gene pool.
