In this selection volume, we have collected ten of Péter Popper's best lectures in one bouquet, which show what an endlessly colorful individual and wise, good-humored teacher the recently deceased psychologist was. The thought-provoking and entertaining chapters are based on an important topic of our everyday life - such as fear, anxiety, depression, individual and collective lies, games, family and relationship conflicts, crises. For many years, until his death, Péter Popper regularly held lectures for the general public, which were awaited with great interest by the public in all parts of the country. At these meetings, often with hundreds of people, he talked about the big questions and problems of life, which can thoroughly crush and injure the human soul. He called these "soul gnawers". Of course, the audience always wanted to know from him what the solution is, how we can protect ourselves against soul gnawers, and how we can heal the wounds caused by them. And he, if he knew the antidote, the medicine, if he knew some secret practice, then he revealed it. If not, then he admitted without embellishment and treasury optimism: he does not believe that there is a solution to all of life's problems. There are also situations that can only be endured, good or bad. However, teaching is never superfluous, as it provides comfort in addition to information and solutions. , helps us rethink and reevaluate things, and we all need that.
