It's a basic principle of behavior, what you attend to tends to be increased. Certaintly we need to be aware of the problems. It is toxic to live the "Good Vibes Only" life/attitude, but that isn't to undermine this message. We must reinforce what we want to see in the world. Differential reinforcement is a valuable strategy that improves outcomes and increases skills aquisition.
"Reinforce what you want to see in the world."
