In an interview, Charlie Munger discussed his investment philosophy, stating that experiencing market fluctuations of 50% is normal in the long run. The real test lies in whether you can maintain a calm mindset during the massive shocks that inevitably occur every one or two centuries.

Munger bluntly stated that if you can't remain calm in the face of a halved market value, you don't deserve to be a true shareholder and are destined for mediocre returns. This is not only investment discipline but also a tempering of the mind. Market fluctuations are like the laws of nature; truly excellent long-term holders know how to maintain a philosopher's composure in the face of storms.

Ultimately, what sets people apart is not technical analysis, but rather the deep-seated calmness and composure in the face of volatility. This is the true foundation for navigating cycles and achieving extraordinary returns.
