Signs you've crossed the line into the writing zone:
-You send your kid to school, knowing they don't feel well, so you can have your morning writing time. (Hey, he didn't have a fever, and wasn't throwing up or bleeding. I did tell him I would come and pick him up if he really needed me to.)
-You are a notorious do-not-disturb-before-10am weekend person but now wake up at 7am to write in silence while everyone else sleeps in.
-You have always been night writing person, but when life hands you a quiet morning schedule, you find yourself staring at a wide-awake morning writer person on the mirror. When the hell did this atrosity happen?
-You bring your kid to the money pit known as Chuck E. Cheese on a busy weekend and hand her $10 so you can have half an hour of writing time surrounded by the not quite white noise of fifty pizza-smeared kids screaming in glee. Sadly that half an hour also included turning in the tickets and five minutes of picking out trinkets. (We'll know I'm in real trouble when I sink to giving her $20.)
-And the final nail in the coffin: You are a professional procrasintator but now barely get on the internet because you'd truly rather be writing. (Sorry, all my usual procrastionation sites, I'll be back... eventually.)
