My Head is Empty

Have you ever started to do something and realized your head is empty? Not sure what causes this condition but I'm suffering from it now. I don't think my mind works good in the heat. There are those who would argue that it doesn't work that good when it's cool either.
I did shoot a photo the other morning while on the way to work. He looked at me as if to say. "Hey man, you're stopping traffic. Is your head empty?"
I used to pass up photo opportunities the later I would kick myself saying "what's wrong with you?" It only takes a second.
There is a photo waiting to happen near my house. I've almost stopped a couple times. There is a lake with baby ducks that swim near the shore. I get to the lake just as the sun is rising and the mist from the lake is hovering just above the surface. I've stopped a few times, but the shot has not been right. The ducks are too far away or the mist is too heavy to get the shot. I have patience so I know it will happen....hopefully it will before the baby ducks have babies of their own.
Y'all stay cool.
