Complex systems (weather, the economy, your life) are not linear. * Linear: Throw a ball 2x harder, it goes 2x far. * Non-Linear: Throw a ball 2.0001x harder, and it might hit a bird, which startles a cat, which runs into the road, causing a traffic jam...
The "Sliding Doors" Moment
Think of a choice you made 5 years ago. Maybe you said "Hi" to a stranger at a party. * That stranger became your boss. * Or your spouse. * Or they gave you the flu, causing you to miss a flight that later crashed. You are constantly navigating a branching tree of infinite probabilities.
