Take a look at something you started writing and didn’t finish for some reason. There can be many reasons for this – a change of circumstances, illness or a feeling that whatever you were writing was rubbish and you didn’t bother to finish it.
Go back to it and strip it down to its core. Imagine you’re writing a logline for a film script. Write a couple of sentences about who the characters are, what conflicts they are facing and where the action is taking place. For instance: Molly Travers and her children escape from their house as fire devastates the city of Coventry following a WW2 bombing raid. She is determined to make a new life for them.
Then add the plot elements – how, when and why and see where the idea takes you.
Aim to create a short outline.
