The most important three words in investing is: 'I don't know,' If someone doesn't say that to you then they are lying.
Core idea
The core idea is that honest investors admit uncertainty; anyone claiming perfect knowledge about markets is misleading you and ignoring the inherent unpredictability of investing.
Practical application
To be a better investor, admit "I dont know," stay humble about forecasts, question confident predictions, diversify, and update decisions as new information proves your uncertainty was justified.
Why it matters
The insight is that recognizing our ignorance about markets is a crucial edge, forcing humility, risk control, diversification, and adaptable thinking instead of overconfident, dangerous certainty.
