Stop Searching for Eternal Laws! The Ultimate Self-Rescue in The Psychology of Money: Stay Flexible and Prepare for the Unexpected Rogue Waves

I used to spend a massive amount of time studying stock charts and financial reports, desperate to predict the next peak of the market.

Looking back, the results were negligible. In fact, it pretty much proved that retail investors like us are usually just puppets on a psychological stage carefully set up by big players, walking in only to be harvested.

It wasn't until I read The Psychology of Money that I truly cooled down. There is a line in the book that is brutal but incredibly true:

"You prepare for the risks you can imagine, but it is the risks that occur outside of your imagination that matter. In a word, risk is what's left over when you think you've thought of everything."

Simply put, risk cannot be predicted in this world. By the time you think you are ready to prepare after making a precise prediction, risk has already escalated into danger.

Sudden Catastrophes and the Long-Term Snowball Effect¶

Many people seek "certainty" in investing, hoping for a neat and perfect conclusion when bad things happen. But the reality is that the world goes through a major crisis roughly every 10 years. The pattern is there. Yet because the probability of it happening on any given day is extremely low, people always gamble and assume, "I won't be that unlucky." Consequently, a series of unpredictable events chain together, producing a rogue wave more dramatic than fiction.

Warren Buffett famously used the "snowball" analogy to describe the power of long-term thinking. Major positive events require the compounding effect of many small things over a very long time, making them easy to ignore amidst daily noise.

In 2026, looking at the current AI wave around us, this feeling is even stronger. This AI boom has to last long enough, because everyone knows that if it falls, it will fall incredibly hard. As the book states: "Things that can’t go on forever can go on much longer than you think." In this tug-of-war, do you still want to place your bets on predictions?

There Are No Eternal Laws, Only the Flexibility to Keep Learning¶

Some say that many laws in the world are like Newton's laws — they only hold under human everyday conditions and break down once you approach the speed of light, requiring other laws to compensate. So, is there an ultimate core law in investing or the workplace that never changes?

Honestly, no.

Because the essence of everything is change. As market pressure increases and people get smarter, formerly solid laws are even more likely to fail. If we must name one thing that remains unchanged, it is "continuous learning." In the face of unknown risks, don't try to predict the future. Instead, keep yourself flexible, keep learning, and keep observing. The more agile you are, the less you need to know what happens next.

The "Margin of Safety" under Modern Pressures¶

The book's ultimate solution is the "margin of safety" — to "plan with pessimism, dream with optimism."

It sounds lofty, but when dealing with real-world risks under the heavy pressure of supporting multiple generations today, it ultimately boils down to that old, simple rule: keep 3 to 6 months of emergency funds.

This is not just for investing; it is to keep your life from becoming fragile. When an unexpected rogue wave hits you, this buffer fund is your final moat. We are terrible at predicting, but we can hold onto core principles through long-term habits to ride out the storm.
