Just a quick note: Thanks for the words of support about the writing block/crisis of confidence. I really appreciated hearing from people about their experiences. I think it is one of the big benefits of the internet to make this incredibly isolated endeavor something that can be shared.
And the good news is that on this stinky hot and humid day, I've got the critters at camp, the AC on, and I've managed to pick my writer self up off the ground, dust off my keister and get back to writing. It isn't flowing like the magical day a few weeks ago, but it is moving and I feel a direction and shape and purpose.
