If you usually write between five and seven o'clock in the morning, but for some reason have a glitch in your schedule and for a week or month have free time from five to seven in the afternoon, please change your schedule. Do not think, I can't write at this time. Do not think, I'll just take a month off of writing until I get back on track with the schedule that works for me.
Any two free hours to write should work for you. Maybe it's a sign. Maybe you had to quit writing between five and seven in the morning because a deranged sniper is traveling around your area, shooting at houses before dawn. Don't let the deranged sniper make you quit writing altogether.
