One of the most important things we get from this world is feedback. Information about how we're doing. What people like, and don't like. How to make things better.
As a kid, falling on the ground, scratching your knee - that's feedback. "Ouch! The world hurts!" you think. Or, "Hmmmm ... concrete is hard. Skin is soft. Concrete and skin don't quite match up nicely all the time." And you change your behavior accordingly.
Feedback is brilliant. Feedback is crucial. It's the map between our thinking and the world, telling us clues about what's going on beyond our minds.
