Every other Wednesday, I attend a writer's group. I would recommend a writer's group to any writer who is starting out. After writer's group last night, a few of us hung around and talked about the tone of our particular group. In our group we make sure we encourage one another and give positive comments along with suggestions for change. Even though we are an extremely diverse group, it really has become a "family" like atmosphere. I can't imagine it any other way.
As writer's we already have enough discouragement and doubt about our work (most of that negative energy coming from ourselves). So make sure when you are meeting with a group that it is one that will uplift and encourage you, not make your doubts turn into road blocks that will bring you to a screeching halt in your progress.
Speaking of road blocks/writer's block. I notice that I get the most writer's block when I'm worried about what other people will think of a certain part of my story. So I try to put everyone else out of my mind when I write. It seems to help. What about all of you? When do you experience writer's block and how do you get through it?
