Salon has an article on novelists using software programs to deny themselves access to the Internet.
This is what I need. I wrote my second book — Antonio’s Gun and Delfino’s Dream — in a cafe mercifully before the era of Wi-Fi hookups.
My focus was deep, as I listened to music via headphones and wrote for 5-6 hours at a time for weeks. I remember reaching profound levels of concentration doing that.
Now, Wi-Fi allows us to cut away at any moment when the writing gets tough. Very frustrating and counterproductive.
