Uninspiration and Suffering and Also Batman and Cornflakes

This is me and my husband when writing's going wrong and the words won't flow:

And this is me when the writing's going fine:

(That is not a mini-skirt that is a big belt on top of jeans to hide the Batman Utility Belt and this is a run-on on purpose thank-you very much)

And me with a rejection letter? Just shrugs, and "I'll try again."

It's weird how the worst criticism is the criticism that comes from within. The agents and editors have things to do, and I understand if I don't match them, or if we can't work together. But when I can't please myself--

Good gracious there's heaven to pay.

What about you? What does writing do to YOUR sanity and family-life?
