Writers always need a second set of eyes. As you write your stories, you will often get into a rut and only see things one way. Of course your story is perfect. You wrote it! You love it! That is to say until an editor or agent sees it and sends you that wonderful rejection letter (if you are lucky they didn't ghost you). So what do you do? You go out and get a critique group together. Your goal as a group is to work together to craft the best damn books ever!
Sounds like a great plan, right?
You might want to stop for a minute and think before you leap. You see, critique groups are only as good as the members in the group.
What I have seen, unfortunately, is that many of these critique groups are often nothing more than "the blind leading the blind." In other words, if none of you really understand the craft of writing, or you have people in your group who believe they know everything (but really know nothing), you are just giving each other bad advice.
Don't get me wrong, we need these groups. We need people who are there to motivate us and keep us writing. BUT, if we are looking for advice to make our stories better, we need to always ask if this person we are talking to really knows "their stuff."
I will also add, I see this same thing happening at many conferences lately. Coordinators go out and get people to lead workshops because the proposals sound amazing. What they forget to look at is whether or not these people are really going to give the participants GOOD advice that will advance their careers and their writing, or are they leading them into a brick wall?
As you look to form your groups or to find those critique partners, look for someone who has shown signs of quality success. Don't just listen to what they tell you. Look essentially at their resume. Do they really know what they are talking about? If not, you can always keep them around as the motivators in your writing life, but be cautious of the advice they give to you. It might not be what you need!
