I came to this realization today as I was talking with my brother-in-law about the writing block that I hit on my newest project (Dark Side Station). In just a few minutes of conversation, he got me past one of the large hurdles that I was dealing with in the story. That was what my writing circle used to do for me.
I don't see my founding another writing circle in the near future. While this could easily just become another excuse to keep me from writing, I shouldn't need a writing circle to keep me going. Still, it was nice when I had one.
