Forget what it was. Look at what it is.
If the light is great in front of you, you should turn around and see what it is doing behind you.
Always shoot it now. It won't be the same when you go back.
There are rules about perception, but not about photography.
Gesture is not always action.
There is no bad light. There is spectacular light and difficult light. It's up to you to use the light you have.
