The stock market is a 'hyperobject'—a phenomenon too vast and complex to be fully understood through data alone. Top investors navigate it by blending analysis with deep intuition, honed by recognizing patterns from countless low-fidelity signals, similar to ancient Polynesian navigators.

Even in hyper-quantitative fields, relying solely on logical models is a failing strategy. Stanford professor Sandy Pentland notes that traders who observe the behavior of other humans consistently perform better, as this provides context on edge cases and tail risks that equations alone cannot capture.

This visceral experience of investing $50 or starting a micro-business provides far deeper insights than purely theoretical or cerebral learning. Combine this hands-on experience with mentorship from pros.
