If you lack a grand goal in living, you lack a coherent philosophy in life. Without one, there is a danger you will mislive and you will end up living a bad life. While enjoying the companionship of loved ones, then, we should periodically stop to reflect on the possibility that this enjoyment will come to an end. By consciously thinking about the loss of what we have, we can regain our appreciation of it, and with this regained appreciation we can revitalize our capacity for joy. Our most important choices in life, according to Epictetus, is whether to concern ourselves with things external to us or things internal. Suppose you find out that someone has been saying bad things about you. Epictetus advises you to respond not by behaving defensively but by questioning his competence as an insulter. To help us advance our practice of Stoicism, Seneca advises that we periodically meditate on the events of daily living, how we responded to these events, and how, in accordance with Stoic principles, we should have responded to them.
