The term 'They Take Things in Stride' can be summarized by the word 'Stoics', which is a six-letter word. Stoics were an ancient Greek school of philosophy that believed in living a life of virtue and accepting life's hardships with equanimity. They believed that one should not be controlled by their emotions, but instead strive to live a life of reason and virtue. This idea of taking things in stride is still relevant today, as it encourages people to remain calm and composed in difficult situations.
