So late last night, not super-late but late enough that I wanted to go to bed, I finished a lot of NotWriting stuff, took a shower, and connected head with pillow. What comes to my tired little mind but the key piece of the key scene in the story I never had time to work on all day? Experience dictated that I would not remember this bit of information in the morning and must get up and write it down right this minute.
If anyone ever tells you that writing is conducive to a full and regular sleep schedule, LAUGH at that person. Heartily. Without further comment.
