In this book, professor and director of the German Polytechnic University in Munich, Wolfgang Heckl, proves that handmade and repairing old things have many advantages compared to buying new. Heckl shows by personal example how manual labor returns people's independence, develops mental abilities and creative skills. And buying a new expensive thing to replace something that is slightly worn out or in need of repair will only cause a momentary surge of joy - as psychologists have proven, an endless series of new purchases cannot make us truly happier. The book contains the most important ideas, the use of which helps to save resources and gives things special value. The book is intended for everyone who likes to create or repair things with their own hands and is conscious of the environment. It is published in Russian for the first time.
