Even I had doubt. I spent the entire morning as well as the entire evening waiting for good light for a panorama I was after. It never came. I took a pano anyway but it's very very uninteresting.
The good news is that I still enjoyed myself even though not much came of it. Here's a non-panoramic photo that I took while hoping that the light would break through the overcast and fog. It never did. Nothing special or really that good of a photo but it's better than not pressing the shutter button at all sometimes
