im currently in the middle of a contest where i literally have to write a novel in three days  last year a day and a half was taken up by that being the only possible timeframe where i could move i made the finals  this year i have a million things on my plate and the story i picked starts out really really hard before it gets easier so four hours maybe five if i push it left in the second day less than half the time left and somewhere between one half and one third of my writing is done  good news is it gets easier as i get closer to the ending
