Of course I do! Initially. When it is very personal. When it hits a nerve. When I know it is "one of my truths that has to be told." Then fear hits first, as usual and rushes around, checking out this and that. "Oh, really now. I can talk about that here? I don't think so."
Insecurities, at the beginning. In the middle, and I am sure, sometimes at the end. Like, I just didn't write my answer.
I read most of the responses first, but I admit, I pretty much kept true to my original thought. I don't change it to fit in with the flow anymore.
Coming back into writing again, and reading...ok..you get the picture. Great question!
