Stoicism is a practical philosophy that helped ancient sages solve life problems and overcome difficulties. The Stoics called for developing sanity and discipline, distinguishing what we can change from what is beyond our control and acting decisively. Having learned the philosophy of Seneca, Epictetus and Marcus Aurelius, modern man can strengthen the spirit and body, overcome the chaos of everyday life, develop concentration and streamline his life. This will be helped by the book of Marcos Vasquez, who combined the principles of the Stoics and the concepts of modern psychology. In it, you will also find mental techniques and exercises that will help develop awareness and protect the mind from anxiety, stress and temptations.
