Suffering rejections, harsh critiques and bad reviews is part of the life of the writer. I've come to realise that the old saying that you can only please some of the people some of the time can be a writer's greatest comfort.
One story I recently submitted for critiquing is a good example. The critiques I received are split down the middle between 'this is great, just needs a couple of tweaks' and 'what is it about? I don't get it, needs completely rewriting'. It's the clearest split I've seen yet in critiques. Now I need to find a magazine editor who shares the opinion of the first group.
