Never say you're going back - SHOOT IT NOW!
There are rules about perception, but not about photography.
The pictures are everywhere. If you're open, they will find you.
What you're shooting at doesn't matter, the real question is: 'Does it give you joy?'
Pain is not a conduit to art or joy
You sort of have to be always aware, even when you're not thinking of shooting. That's when the best stuff happens.
