The book includes two works by the philosopher D.S. Gusman - “How to get to know yourself better” and “Advice for the heart and mind.” “Know yourself” - the inscription on the ancient temple of Apollo in Delphi has not become outdated over the millennia and continues to help us search for the meaning of our existence. The book talks about what it means to “get to know yourself,” what limitations and strengths we can find in ourselves, and how we can cope with the former and develop the latter. But knowing yourself is only the first step. The second part of the book tells what internal reference points will help us change for the better not only ourselves, but also the world around us.
