Just finished my first draft after 3 years and 2 months. The first chapter was 2 years in the making and very stop start.
My biggest challenge has been grammar. It has never been my greatest strength but i'm working on it and improving all the time.
Now time for some serious editing editing and more editing.
How long did your first draft take?
What was your biggest challenge?
Well done for finishing it. I have only written one short story which took me 4 weeks.
