This article was in today’s Guardian. I recognize many of the thoughts of Tim Lott, who wrote it.
The comments at the bottom of the article are worth reading (expand them),particularly the one about the 60% of people who want to be writers,imagining that it’s all J K Rowling easy-peasy wealth and celebrity. It wasn’t for her,when she was trying to find a publisher for her first Harry Potter book,though fortunately that turned into a publishing juggernaut which will keep her for the rest of her days.
The John Dos Passos observation quoted made me snort in recognition at the truth of it : “Writers are like fleas, they get very little nourishment from one another”.
