I am literally the laziest writer on the planet. I marathon my novels over weekends, or a course of weekends...and then do nothing for sometimes weeks. I have never been motivated in life. By anything, really. I am deeply passionate about writing...but only if I can spend insane chunks of time on it at a time. 72 hours = 50,000 words...and then nothing for weeks. My motivation often comes from commitments and deadlines. My agent just told me she was looking for a novel...so I wrote one. Went to a cottage two weekends in a row and pounded one out. Then for a week I edited like mad...three passes...then sent it. NOW----I will vegetate for a while and be lousy with the lazy.
