I noticed recently a wave of tweets all pointing back to this article: Matt Haig: 30 things that every writer should know. Matt Haig is a journalist who has had several books published since 2005 starting with The Last Family in England. The articles is a list of points some of which are more interesting than others but all are drawn from Matt’s experience.
If you read to the bottom you will find that the article is drawn from a longer piece on Book Trust.
