I sometimes take a shot that isn't going to be good due to light conditions etc, but what it is is a record of seeing that subject on that day. Other times I might take a photo with the wrong lens, so I know it isn't going to be great but well aware that if I change lenses I will miss the shot.
Should also point out, that when you take a shot that lots of others have taken, doesn't mean that you can't get a better one, as the lighting will be different on the day you took your shot. Otherwise, we might as well sell all out equipment and sit infront of the telly.
