I read the quote "Moods don't believe in each other" in a great blog by known photographer Stephen Voss.
It's like this. When you're madly in love with someone, you can't imagine feeling heartbroken. When you're depressed or desperate, you can't imagine feeling joyful.
Stephen Voss had worked on a private project on the side for a long time. That wasn't always easy to do. He writes how he found a way, struggling in the messy middle.
He did it without a Vizsla.
Worth your time!
