Stoicism vs Existentialism: How to Actually Live Your Life

You’ve probably felt it: that knot in your stomach when a project goes sideways, or the blank stare at 2 AM wondering if you’re even on the right path. Life throws curveballs, and sometimes, the usual advice just doesn’t cut it. We’re not looking for platitudes here. We’re looking for a way to stand firm, to make sense of the chaos, and to actually do something about it. That’s where ancient wisdom, specifically the clash between stoicism vs existentialism, comes into play. These aren’t dusty academic theories. They’re frameworks for living, for navigating the daily grind and the big, scary questions.

When Everything Goes Wrong: The Bad Email Scenario

Let’s say you wake up to an email. It’s from a client, and it’s bad. Not just ‘needs revision’ bad, but ‘project is on fire, and it’s somehow your fault’ bad. Your stomach drops. Your first instinct might be to panic, to lash out, or to crawl back under the covers. How do you handle that gut punch?

A Stoic would tell you to hit pause. Immediately. Your reaction, that surge of anger or fear, isn’t the event itself. It’s your judgment about the event. Epictetus put it simply: ‘It’s not what happens to you, but how you react to it that matters.’ The email exists. The client is upset. These are external facts. You can’t control the client’s mood or the past actions that led to the fire. What you can control is your response. You can choose to breathe. You can choose to analyze the problem rationally. You can choose to draft a calm, solution-oriented reply. You focus on your duty: to fix what you can, to learn from what went wrong, and to maintain your inner peace regardless of the external storm. It’s about recognizing the sphere of your influence and sticking to it. You don’t waste energy on what’s outside that sphere. It’s a powerful way to keep your head when everyone else is losing theirs.

Now, an Existentialist looks at that same bad email and sees something different. They see radical freedom and radical responsibility. There’s no pre-ordained meaning to this email, no cosmic plan. It just is. And because it just is, you are utterly free to choose your response. This freedom, though, comes with a heavy weight: responsibility. You are responsible for the meaning you create from this situation. You could choose to see it as a catastrophic failure that defines you. Or, you could choose to see it as an opportunity to demonstrate resilience, to innovate, to redefine your relationship with the client. There’s no ‘right’ way to feel, no ‘correct’ action dictated by some external moral code. You are condemned to be free, as Sartre said. This means you have to invent your own values in the moment. You choose to act, and in that action, you define yourself. It’s not about controlling your emotions as much as it is about owning your choices and creating meaning through them. You’re not just reacting; you’re creating your response, and thus, creating yourself.

The Crossroads: Making a Big Life Choice

What about the bigger stuff? The ‘should I quit my job and start a business?’ or ‘is this relationship actually going anywhere?’ questions. These aren’t about immediate reactions; they’re about charting a course when the map is blank.

For a Stoic, big decisions are about reason and virtue. You’d analyze the situation dispassionately. What’s the most rational path? What aligns with your core values of wisdom, justice, courage, and temperance? If you’re considering a career change, you’d ask: Does this new path allow me to serve others? Is it a path of integrity? Does it foster my growth as a rational being? You wouldn’t chase fleeting desires or external validation. You’d seek what’s truly good, which for a Stoic, is always internal and tied to virtue. You’d accept that the outcome isn’t guaranteed, but your effort and intention, guided by reason, are what truly matter. You’d prepare for potential setbacks, knowing that external events are indifferent. The goal isn’t happiness in the modern sense, but eudaimonia—a flourishing life lived in accordance with reason. It’s a disciplined, almost scientific approach to living.

An Existentialist, faced with the same crossroads, would feel the weight of choice acutely. There’s no pre-existing blueprint for your life. No ‘right’ answer waiting to be discovered. You’re standing at the edge of an abyss, and you have to jump, choosing your own direction. This can bring ‘angst’ or ‘dread’—the profound realization that you are solely responsible for your choices, and there’s no one else to blame if it goes wrong. But this dread is also the source of your freedom. You must choose authentically, not based on what society expects, or what your parents want, or what seems ‘safe.’ You choose based on what you believe will give your life meaning, even if that meaning is temporary and self-created. You don’t look for external validation; you create your own. It’s a terrifying, exhilarating process of self-creation. You are the author of your own story, and every choice is a brushstroke.

The Real Talk: Stoicism vs Existentialism, Where They Hit and Miss

So, stoicism vs existentialism: two powerful lenses. But they’re not perfect, and they’re certainly not interchangeable. I’ve spent years wrestling with both, trying to apply them to everything from client pitches to personal crises.

My concrete gripe with a lot of modern Stoicism is how easily it gets twisted into ‘just suck it up’ or ‘don’t feel anything.’ That’s not what it is. It’s about understanding your emotions, not suppressing them. It’s about directing your energy wisely. When someone tells me to ‘just be stoic’ after a genuine setback, it feels like they’re missing the point entirely. It’s not about being a robot; it’s about being a rational human.

My concrete love, though, is the sheer practicality of the Stoic ‘dichotomy of control.’ It’s a simple idea: some things are up to us, some aren’t. But applying it? That’s a daily practice. When I’m spiraling about a deadline I can’t control because a vendor is late, just asking myself ‘Is this in my control?’ immediately cuts through the noise. It doesn’t make the problem disappear, but it focuses my energy on what I can do: follow up, make contingency plans, communicate. It’s a mental reset button that actually works.

On the Existentialist side, I love the emphasis on authenticity. It’s a constant reminder that I’m not just a cog in a machine, that my choices matter, and that I have the power to define my own values. It’s a kick in the pants when I’m feeling passive or just going through the motions. It reminds me that I’m responsible for my own life, and that’s both terrifying and incredibly liberating.

But honestly, the free plan for just ‘winging it’ through life is a joke. You need some kind of framework. You need to put in the work to understand these ideas. You can’t just read a quote and expect your life to change. For someone just starting out, a good entry point is often a structured journal or a well-curated book. For example, ‘The Daily Stoic Journal’ is $25, and honestly, it’s a fair price for the structure it gives you. It’s not a magic bullet, but it provides prompts that force you to engage with the ideas daily, which, yes, is annoying sometimes, but it builds the muscle.

So, Which One Should You Pick?

You don’t have to pick one and ditch the other. They offer different strengths. If you’re someone who feels overwhelmed by external events, constantly stressed by things outside your influence, or prone to emotional reactivity, stoic philosophy offers a powerful antidote. It gives you tools to build inner resilience, to find calm in the storm, and to act with reason and virtue. It’s about mastering yourself.

If you’re someone who feels lost, unfulfilled, or trapped by societal expectations, if you’re searching for meaning and purpose in a world that often feels meaningless, then Existentialism might be your guide. It pushes you to confront your freedom, to take responsibility for creating your own values, and to live authentically. It’s about creating yourself.

I find myself leaning on Stoicism for the daily grind—the bad emails, the missed deadlines, the annoying people. It’s my shield. But when I’m facing a big, existential question about my purpose or my path, Existentialism is the hammer that forces me to confront my freedom and make a choice. They’re not mutually exclusive. They’re two different tools in the same mental toolkit.

The point isn’t to become a philosophy grad student. It’s to live better. To have more clarity. To act with more discipline. To stop letting life happen to you and start making it happen for you. Or, at least, to respond to it with intention. That’s the real ancient wisdom.
