André Kostolany's final masterpiece is a money management guide that guides you through the fundamental secrets and techniques of investment, which are important variables in stock trading and investment psychology.
The author provides investors with a perspective on the opportunities, risks, changes, ups and downs of the 21st-century stock market.
In this book, the author wanted to share his knowledge about stocks and various investments.
He also depicts world-historical events related to money, people who pursued money and wealth and either acquired it or failed, and, above all, his own numerous experiences from his investment life, all in a uniquely humorous style.

In my experience, there are three ways to become a millionaire in a short period of time.
1. Marrying a rich man.
2. Promising business items and ideas.
3. Investment.
While you can quickly become a millionaire by inheriting an inheritance or winning the lottery, unlike the three methods mentioned above, these are outside of your control, so we'll exclude them.
Many women and men become millionaires through marriage.
I have seen countless cases like this.
When it comes to people who became rich through a promising business idea that was met with luck, Bill Gates comes to mind more than anyone else.
With one business idea and sharp intuition, he became one of the richest people in America in his 30s.
Or think of Sam Walton of Walmart or the founder of McDonald's.
Erno Rubik, a genius Hungarian engineer, became the first millionaire in Eastern Europe 20 years ago with the magic dice he invented.
But a brilliant idea alone isn't enough.
Such an inventive spirit must be combined with a business brain.
For example, the pharmacist who developed the recipe for Coca-Cola sold the recipe to the now world-famous brand for a mere few dollars.
There's nothing more to say about how to build wealth with clever and smart business ideas.
Because my specialty has always been investing, which is the third and final method.

People who don't know much about stocks often describe the stock market as an economic thermometer, but that's not actually the case.
The stock market does not show the current situation or the future economic trends.
To prove this, we don't need to delve into ancient history; we only need to look at the past five years.
While Germany achieved tremendous economic growth and unemployment remained high, its stock market grew by a staggering three times.
And this is precisely what Oscar Lafontaine was vocally criticizing during the last federal election campaign.
But he doesn't understand anything about the stock market, let alone the economy.
In contrast, in the United States, the economy grew and the stock market boomed during times of full employment.
But there have been cases where the economy was booming but the stock market was depressed.
The economy and the stock market do not always grow in parallel.
That doesn't mean there's no interaction between them.
Let me explain this more easily using an example from a story I recalled several years ago.
A man walks his dog.
As is typical with dogs, his companion runs towards his owner and then returns to him.
Then he runs forward again, realizes that he has moved away from his master, and returns to him.
This behavior continues throughout the walk, and at the end, the two arrive at the same destination together.
But while his owner walked slowly for one kilometer, the dog ran around and walked four kilometers.
Here, the master is the economy and the dog is the stock market.
A look at the development of the American economy during the Great Depression of 1930 to 1933 illustrates how accurate this example is.
The economy is constantly developing, but it sometimes stops for a step or two and sometimes takes a step back.
But the sovereign market fluctuates up and down more than 100 times in the same period.

No matter what restaurant I go to, I never order what the waiter recommends.
Because such menu items are usually sold out quickly at the restaurant.
The same goes for 90 percent of the stocks or investment advice recommended by securities firms.
Good advice worth taking note of is really rare.
In most cases, it is nothing more than a ploy or publicity stunt to get people to buy shares in a bank or syndicate.
This is done by framing it with a rosy analysis and then spreading it through the media by word of mouth.
And they cleverly control the news in the direction they want and manipulate stock prices.
Then, even if the stock price has already risen as much as it can, selling it to the public is a piece of cake.
Fueled by this type of buying, stock prices soar through the roof.
After the buhwanodongpa investors have bought all the stocks, it will be revealed at some point that their rosy analysis was nothing more than hot air, and they will inevitably go bankrupt.
