I'm trying to think of the longest stretch that I've been able to write without an interruption. I'm sure there are times that I've been lost and swimming in hours-long sessions, but it seems rare.
Mostly I just pick up the pen, put on my thoughtful expression, and the phone rings or an email alert beeps. I think that's why I have to get out of the house to write. I feel like a man on a mission and I can't come back without my words of prey.
How do you make the time to write and keep from being interrupted?
