Charlie Munger said we need a latticework of mental models. The beauty of science is that it gives us patterns that do not stay inside textbooks. They spill over into daily life, career, and relationships.
1. Entropy
Left on its own, everything drifts toward disorder. Your room, your body, your projects - they do not maintain themselves. If something matters, schedule the upkeep. Order is never free.
2. Critical Mass
Big shifts often feel sudden, but they are the result of small pushes stacking up. Building an audience, forming a habit, or launching a product works the same way. Most people quit before hitting that invisible threshold.
3. Feedback Loops
Biology runs on feedback. Some loops stabilize you, while others amplify until they spiral out of control. Life is no different. Recognizing which loops you are inside is half the game.
4. Limiting Factor
In chemistry, reactions stop because one ingredient runs out. In real life, growth is often constrained by one scarce input. Instead of trying to optimize everything, find the bottleneck and fix that first.
5. Inertia
Objects at rest stay at rest, and objects in motion stay in motion. Starting a project is often harder than doing the project. Lower the barrier to starting and momentum becomes more available.
6. Natural Selection
Nature discards the inefficient, and so does the world. Careers, businesses, and personal habits all face the same filter. Test small variations, keep what works, and let the rest die quietly.
