58 - Mental Models are internal structures our minds form about reality that helps us predict and navigate a world full of complexity. There are three central explorations that I think about with mental models: understanding of the model, when to use the model, and what models are worth internalizing.
You have to prioritize what mental models you internalize because creating knowledge, which is a step beyond information structures, takes time and effort. You want to memorize the models which have the most applicability (e.g. general thinking concepts) or are of high value (e.g. highly desired skills).
