The 21st century styled version of classical life philosophies.

Humanity has been searching for the answer to the question of how to make its life better and happier since ancient times.

How should I live?
What will make my life better?
What role does fate play?
How important is money?
Is a good and happy life a matter of attitude, personal attitude, or rather the achievement of tangible successes and life goals?
What is better? Is it if we pursue happiness or if we try to avoid unhappiness?

Every generation asks these questions, but the answers are always disappointing, because we are always looking for a principle, a basic theorem or a rule. There is no such thing, the world is too complicated for that. There are many, often surprising, paths to happiness. The author with a readership of millions now conjures up the best 52 thinking tools to help us face the challenges of the 21st century in his book, armed with a lot of humor. Although they do not guarantee a happy life, they make it much more likely!

This way of thinking and behavior can also be called the "operating system of life". However, I like the old-fashioned toolbox analogy much better. The most important thing is that the mental toolbox and its tools are more important than material knowledge. It is more important than money and more important than relationships and intelligence.
