I have just reread one of my favourite books - Edith Wharton's The Age of Inocence, which won a Pulitzer Prize. And when I went back to my own book - the one I am currently writing - I was so discouraged, I wanted to give up being a writer, and sink into oblivion. (Voice from the corner - What makes you think you're not already in oblivion?)
I told my writer friend Chrissie and she said simply "Perhaps you shouldn't be reading Edith Wharton when you're trying to write." A wise woman.
