I had this fear with a recent two-part story. I worked on it for along time, and even when I finished, I was sure if I could post it. It was quite personal.
On the other hand, my most successful stories have been personal.
It's not so much that I fear writing about myself, but very personal stories also reveal things about others. That can be difficult. I asked for this; they didn't.
Have you ever felt that way?
