The Purpose of Life: Insights from a Coursera Course

The question of life’s purpose has always fascinated humans, and I am no exception to its mystery. In recent times, witnessing birth and death up close has made it even more intriguing. I have spent considerable time reading about it, and during this journey, I came across a Coursera course titled “Purpose of Life.” Below are my notes from this course.

To expedite learning and condense the content, I used NotebookLM as a tool. This exercise is also part of an experiment I’m conducting to explore my love for learning while minimizing the time investment. And believe me, it has been an absolutely fascinating journey so far.

Definition of Purpose of Life

A central, self-organizing life aim.

The course explores how the idea of purpose has evolved over time. Five hundred years ago, purpose was largely shaped by external forces—God, society, and family. A hundred years ago, Nietzsche famously declared, “God is dead,” leading to a crisis of meaning in society. However, this also gave individuals the freedom to define their own purpose.

A beautiful analogy is used to illustrate this evolution:

• Camel – Represents the phase of eagerly seeking knowledge.
• Lion – Symbolizes questioning rules and finding one’s own voice.
• Child – Stands for the creation of one’s own purpose.

The philosopher Albert Camus argued that one can find meaning even in absurd situations.

Guiding Principles for Finding Purpose

A framework for creating one’s purpose involves aligning personal goals with core values.

Some key approaches mentioned in the course include:

• Curiosity – Exploring different interests.
• Self-reflection – Understanding oneself better.
• The Headstone Test – A method to clarify values by asking: What kind of mark do you want to leave on the world?

The course emphasizes that purpose is a powerful force deeply rooted in both our biology and culture. It also highlights the importance of ethical frameworks, religion, and philosophy in shaping purpose. A strong sense of purpose, however, must be guided by values—Hitler, for instance, had a strong purpose but lacked moral guidance.

Having a diverse portfolio of purposes can also be beneficial, allowing flexibility as life changes.

Scientific Insights on Purpose

Research suggests that people with a strong sense of purpose:

• Make healthier choices.
• Manage stress better.
• Report higher levels of life satisfaction.

One quote that resonated deeply with me is from Walden by Henry David Thoreau:

“The cost of a thing is the amount of… life which is required to be exchanged for it, immediately or in the long run.”

Studies show that purpose has tangible effects on the brain, particularly in reducing stress. Simply reflecting on one’s purpose can lower stress levels, especially in diverse and unfamiliar environments. Knowing what you stand for helps navigate chaos.

Having a strong purpose also enhances resilience—people recover faster from setbacks when they are connected to their core values. Scientifically, purpose is linked to lower inflammation and a stronger immune system.

Connecting with something greater than oneself consistently brings a sense of meaning. Evolutionarily, this connection has played a role in human survival—people who think beyond themselves are more beneficial to their communities.

However, the course also highlights a decline in purpose among newer generations, who often struggle to find their place in the world. Purpose remains important at every stage of life, but it becomes especially crucial as we age, when shifts in identity, job, and structure impact our sense of meaning.

A lack of purpose in life has even been linked to a doubled risk of developing Alzheimer’s disease.

Finding True Purpose

Purpose must be aligned with one’s true values. How does one find true purpose? The course suggests that it is a dynamic process of self-discovery and reflection. It involves:

• Identifying what brings you joy.
• Applying your strengths.
• Understanding how you can make a difference.
• Defining the legacy you want to leave behind.

This reminded me of some thought-provoking words I noted down a few years ago:

One day, you and everyone you love will die. Beyond a small group of people, and for an extremely brief period of time, little of what you say or do will ever matter. This is the uncomfortable truth of life. Everything you think or do is but an elaborate avoidance of it. We are inconsequential cosmic dust, bumping around on a tiny blue speck. We imagine our own importance. We invent our purpose. We are nothing.

Enjoy your fucking coffee.

Ironically, this quote completely contradicts the idea of life’s purpose. However, I like to look at it this way—research shows the immense benefits of having a purpose aligned with one’s values, but at the same time, we must acknowledge that purpose is ultimately our own creation.

At the scale of the universe, our existence is insignificant. Our impact is negligible in the grand scheme of things. So, while we pursue purpose, we must also ensure that we don’t miss out on enjoying life and experiencing it in its entirety.

Final Thoughts

Purpose isn’t something that is given to us—it is something we create. It provides meaning, enhances well-being, and connects us to something greater than ourselves. But in the end, purpose should not become an obsession. Life is fleeting, and sometimes, the simplest joys—like a good cup of coffee—are just as important as the grand search for meaning.

This was part of my experiment to compress learning time while still gaining meaningful insights—leveraging technology, in this case, NotebookLM, to achieve that goal.
