There is nothing worse than having (what you think is) a great idea for a story, writing at a 100 wpm and then getting stuck three quarters of the way in. And staying stuck for a week.
How many of you start writing only after you know how everything is going to play out?
(I am thinking of buying a ‘How to write’ book. Amazon seems to have just as many titled ‘How not to write.’ I think I already know that)
