Mental Models Quotes
Picture trying to navigate a new city with an outdated paper map. You might still arrive, but you will waste time, miss shortcuts, and take wrong turns you could have avoided.

Why these quotes matter
Your outcomes are downstream of the models in your head. Weak models create indecision and reactive choices. Strong models reveal leverage, reduce noise, and make hard decisions faster.
How to apply them daily
Start a personal model library with 10 essentials and write each in one sentence. Before big decisions, apply at least three models and note what changes. Keep a decision log and review outcomes monthly to refine your models. The goal is not certainty, but better calibration over time.
