Today I have a tip from Carmen Ferreiro-Esteban who blogs at Dare to Read. This is the first tip she's sent in so please visit her sites and consider subscribing. Her most recent post is on querying, which is always a popular topic, so check it out when you're done here.
Writing Tip: Know your ending.
To write a story you need characters, setting and conflict. You also need an ending.
If you don't have an ending you don't know where you are going and, although you may get there by trial and error, it would take you longer and you'll need many revisions for the ending to fit the story properly.
Yes, I know Stephen King does not know the ending of his stories when he starts writing and he seems to be doing all right, but, in my experience 99% of writers block and 99% of unfinished manuscripts are a direct consequence of the author not knowing the end a priori.
