Excellent concept, and well written. I’ve never experimented with micro writing sessions like this because I tend to have trouble getting focused in the first place — once I’m “in the zone” I like to stay there for 40–80 minutes. I’m going to experiment with this though, because I am actually writing my first nonfiction book right now and I’ve been failing to put time into as often as not. I can do 8 minutes a day.
