This Time It's Different
Assuming "this time is different" leads to catastrophic losses.
The four most dangerous words in investing are: 'This time it's different.' Markets cycle. Human nature doesn't change.
🏠 Everyday Analogy
📖 Core Interpretation
Every bubble in history has been justified by claims that old rules no longer apply. They always do.
💎 Key Insight：Every bubble justifies itself with new paradigms, but fundamentals always reassert themselves. Technology, globalization, or innovation may change details, but human nature and economic laws remain constant. When investors claim old rules no longer apply, they are usually at peak delusion. Historical patterns repeat because greed and fear are timeless.
