The human's mind is a pattern-matching machine. We think in a set of mental models. These chunk of knowledge represent a concept. Conways Law is an example of a concept, as is Gravity.
These mental models shape how we think, how we approach problems, and how to identify information that matters or not. The mental models we have in our head are our cognitive skillset. Farnam Street has been essential for my personal understanding of mental models and how we think.
