I'm sure that I am not alone in the feeling that when it comes to judging the quality of my own work, I am easily my worst critic. Obviously, as the creator, you can see everything that is wrong, know how it was supposed to sound in your head, etc.
But seriously. What is it about my bed that seems to make everything better?
More often than I can count have I had an occasion to write something, not be happy with it, tinker, tinker some more... Only to end up frustrated because it's not going where I was hoping it would. So I leave it and go to bed. And then... something magical happens. I wake up, head over to the computer, and suddenly, the very thing that was making me unhappy isn't so bad any more. In fact, it's actually quite good.
Nothing changed. I don't think that my cat wandered over to the computer in the middle of the night and fixed anything for me. But the distance, the time away, somehow that gave me a new perspective on what I had been working on.
I find it amazing how powerful my bed must be!
