Series: Journey Through Stoicism

We spend much of our lives pretending we have endless time. The Stoics knew better. Memento Mori—remember that you will die—was not a grim command but a call to live awake. Modern science now confirms what they intuited: when people recognize their days are finite, they become calmer, kinder, and more grateful.

In this new essay, I explore how ancient philosophy and modern psychology meet on common ground. From Seneca to Stanford researcher Laura Carstensen, the message is the same: awareness of mortality can make life richer, not smaller. Read Memento Mori: Learning to Live by Remembering Death.

Some people quietly shape the way we see the world. Some do it by teaching. Others, simply by being there year after year, when life tests our convictions. The Stoics believed that friendship was a form of moral training and that mentorship was the art of walking beside someone as they learn to live well.

In this essay, I reflect on five people who changed the course of my life. They were friends and mentors whose presence became a daily lesson in philosophy. Their stories align with the wisdom of Seneca, Epictetus, and Marcus Aurelius, as well as with the insights of modern science, proving what the ancients already knew: that deep connection is essential to a good life.

The Stoics called these relationships “friends of virtue.” Today, we call them the people who help us become who we’re meant to be.

When I first began walking, one mile was a struggle. Every step was an argument between my will and my comfort. Over time, those miles became my teacher. What the Stoics called voluntary discomfort is not self-denial but a rehearsal for life’s inevitable hardships. When we choose minor difficulties—a plain meal, a long walk, a day without convenience—we remind ourselves that peace does not depend on comfort. Each act of endurance builds calm, gratitude, and freedom.
