Until then, I look for one day a week where I can mini-burst:  at least 3 hours of dedicated, focused time.  Sometimes all I get is an hour, but longer periods are so much more productive because I can get in ‘the zone’ and stay there, cranking out the words.

For me, a two-hour minimum block of time is most productive.   What have other people found works best for them?  Have you tried burst-writing?  Has it worked for you?
