Pixel commented on How to Make Sense of Any Mess by Abby Covert
"When you discuss a specific subject, you subconsciously reference part of a large internal map of what you know.
Other people can't see this map. It only exists in your head, and it's called your mental model.
When faced with a problem, you reference your mental model and try to organize the aspects and complexities of what you see into recognizable patterns. Your ongoing experience changes your mental model. This book is changing it right now."
