An avid reader. A prolific reviewer (I review for a printed newspaper and several online outlets). A non-stop scribbler in my trusty notebooks. The literary bug has been a welcome lodger in my soul for two decades.
Learning to take criticism from all walks of life is part and parcel of what any writer should expect to do. We might like to know where the reviews come from, but its not always possible. What we have to do is stand by our own writing and use our own judgement, Check out http://lucyvee.blogspot.com/2011/06/dealing-with-feedback-losses-gains.html who gives very sound advice on many subjects. If you published a book, how many reviews would you get from regular readers, with no experience in writing? We are hear to learn from each other, but we're also here to make friends from all walks of life and experience. I have a very close friend and co-writer who was a faceless avatar for many, many years. His advice to other writers was spot on, sometimes he was questioned about his experiences, but it never stopped him sharing or helping others. Now, I know who he is, but I trusted him with some of my ideas long before that. Appreciate any thoughts, feelings, opinions on your work. Take what you want from them, chuck the rest. Always stick to your own guns though, no matter what.
