The image of the Zen philosopher is the monk up in the green, quiet hills, or in a beautiful temple on some rocky cliff. The Stoic, on the other hand, is the antithesis of this idea. The Stoic is the man in the marketplace, the merchant on a voyage, the senator in the Forum, the soldier at the front. In other words, they are like you.

Those jobs might not seem like one well-suited for “philosophy,” but they are. And so are you. For in even the most modern seeming professions, a Stoic is able to find peace and clarity. For thousands of years, Stoicism has been a tool for the ordinary and the elite alive — from slaves to emperors — as they sought wisdom, strength and the ‘good life.’ It was philosophy designed for action — for doers — not for the classroom.

Which is why it has been popular with everyone from Marcus Aurelius and Seneca (one of the richest men in Rome), to Theodore Roosevelt, Frederick the Great and Michel de Montaigne. More recently, Stoicism has been cited by investors like Tim Ferriss and executives like Jonathan Newhouse, the CEO of Condé Nast International. Even football coaches like Pete Carroll of the Seattle Seahawks and baseball managers like Jeff Banister of the Texas Rangers have recommended Stoicism to their players.

How can we follow in their timeless footsteps? How can we reap the benefits of this operating system in our own workplace? It’s simple. Go to straight to the sources. Below are Stoic exercises and strategies, pulled from the new book The Daily Stoic (and daily email at DailyStoic.com), that will help you navigate your workplace with better clarity, effectiveness, and peace of mind.

DON’T MAKE THINGS HARDER THAN THEY NEED TO BE

“If someone asks you how to write your name, would you bark out each letter? And if they get angry, would you then return the anger? Wouldn’t you rather gently spell out each letter for them? So then, remember in life that your duties are the sum of individual acts. Pay attention to each of these as you do your duty . . . just methodically complete your task.”

— Marcus Aurelius, Meditations, 6.26

Here’s a common scenario. You’re working with a frustrating coworker or a difficult boss. They ask you to do something and, because you dislike the messenger, you immediately object. There’s this problem or that one, or their request is obnoxious and rude. So you tell them, “No, I’m not going to do it.” Then they retaliate by not doing something that you had previously asked of them. And so the conflict escalates.

Meanwhile, if you could step back and see it objectively, you’d probably see that not everything they’re asking for is unreasonable. In fact, some of it is pretty easy to do or is, at least, agreeable. And if you did it, it might make the rest of the tasks a bit more tolerable too. Pretty soon, you’ve done the entire thing.

Life (and our job) is difficult enough. Let’s not make it harder by getting emotional about insignificant matters or digging in for battles we don’t actually care about. Let’s not let emotion get in the way of kathêkon, the simple, appropriate actions on the path to virtue.

IMPOSSIBLE WITHOUT YOUR CONSENT

“Today I escaped from the crush of circumstances, or better put, I threw them out, for the crush wasn’t from outside me but in my own assumptions.”

— Marcus Aurelius, Meditations, 9.13

On tough days we might say, “My work is overwhelming,” or “My boss is really frustrating.” If only we could understand that this is impossible. Someone can’t frustrate you, work can’t overwhelm you-these are external objects, and they have no access to your mind. Those emotions you feel, as real as they are, come from the inside, not the outside.

The Stoics use the word hypolêpsis, which means “taking up” — of perceptions, thoughts, and judgments by our mind. What we assume, what we willingly generate in our mind, that’s on us. We can’t blame other people for making us feel stressed or frustrated any more than we can blame them for our jealousy. The cause is within us. They’re just the target.

A PROPER FRAME OF MIND

“Frame your thoughts like this — you are an old person, you won’t let yourself be enslaved by this any longer, no longer pulled like a puppet by every impulse, and you’ll stop complaining about your present fortune or dreading the future.”

— Marcus Aurelius, Meditations, 2.2

We resent the person who comes in and tries to boss us around. Don’t tell me how to dress, how to think, how to do my job, how to live. This is because we are independent, self-sufficient people.

Or at least that’s what we tell ourselves.

Yet if someone says something we disagree with, something inside us tells us we have to argue with them. If there’s a plate of cookies in front of us, we have to eat them. If someone does something we dislike, we have to get mad about it. When something bad happens, we have to be sad, depressed, or worried. But if something good happens a few minutes later, all of a sudden we’re happy, excited, and want more.

We would never let another person jerk us around the way we let our impulses do. It’s time we start seeing it that way — that we’re not puppets that can be made to dance this way or that way just because we feel like it. We should be the ones in control, not our emotions, because we are independent, self-sufficient people.

KEEP IT SIMPLE

“At every moment keep a sturdy mind on the task at hand, as a Roman and human being, doing it with strict and simple dignity, affection, freedom, and justice — giving yourself a break from all other considerations. You can do this if you approach each task as if it is your last, giving up every distraction, emotional subversion of reason, and all drama, vanity, and complaint over your fair share. You can see how mastery over a few things makes it possible to live an abundant and devout life — for, if you keep watch over these things, the gods won’t ask for more.”

— Marcus Aurelius, Meditations, 2.5

Each day presents the chance to overthink things. What should I wear? Do they like me? Am I eating well enough? What’s next for me in life? Is my boss happy with my work?

Today, let’s focus just on what’s in front of us. We’ll follow the dictum that New England Patriots coach Bill Belichick gives his players: “Do your job.” Like a Roman, like a good soldier, like a master of our craft. We don’t need to get lost in a thousand other distractions or in other people’s business.

Marcus says to approach each task as if it were your last, because it very well could be. And even if it isn’t, botching what’s right in front of you doesn’t help anything. Find clarity in the simplicity of doing

NEVER DO ANYTHING OUT OF HABIT

“So in the majority of other things, we address circumstances not in accordance with the right assumptions, but mostly by following wretched habit. Since all that I’ve said is the case, the person in training must seek to rise above, so as to stop seeking out pleasure and steering away from pain; to stop clinging to living and abhorring death; and in the case of property and money, to stop valuing receiving over giving.”

— Musonius Rufus, Lectures, 6.25.5–11

A worker is asked: “Why did you do it this way?” The answer, “Because that’s the way we’ve always done things.” The answer frustrates every good boss and sets the mouth of every entrepreneur watering. The worker has stopped thinking and is mindlessly operating out of habit. The business is ripe for disruption by a competitor, and the worker will probably get fired by any thinking boss.

We should apply the same ruthlessness to our own habits. In fact, we are studying philosophy precisely to break ourselves of rote behavior. Find what you do out of rote memory or routine. Ask yourself: Is this really the best way to do it? Know why you do what you do — do it for the right reasons.

YOUR CAREER IS NOT A LIFE SENTENCE

“How disgraceful is the lawyer whose dying breath passes while at court, at an advanced age, pleading for unknown litigants and still seeking the approval of ignorant spectators.”

— Seneca, On the Shortness of Life, 20.2

Every few years, a sad spectacle is played out in the news. An old millionaire, still lord of his business empire, is taken to court. Shareholders and family members go to court to argue that he is no longer mentally competent to make decisions — that the patriarch is not fit to run his own company and legal affairs. Because this powerful person refused to ever relinquish control or develop a succession plan, he is subjected to one of life’s worst humiliations: the public exposure of his most private vulnerabilities.

We must not get so wrapped up in our work that we think we’re immune from the reality of aging and life. Who wants to be the person who can never let go? Is there so little meaning in your life that your only pursuit is work until you’re eventually carted off in a coffin?

Take pride in your work. But it is not all.

PROTECT YOUR PEACE OF MIND

“Keep constant guard over your perceptions, for it is no small thing you are protecting, but your respect, trustworthiness and steadi- ness, peace of mind, freedom from pain and fear, in a word your freedom. For what would you sell these things?”

— Epictetus, Discourses, 4.3.6b–8

The dysfunctional job that stresses you out, a contentious relationship, life in the spotlight. Stoicism, because it helps us manage and think through our emotional reactions, can make these kinds of situations easier to bear. It can help you manage and mitigate the triggers that seem to be so constantly tripped.

But here’s a question: Why are you subjecting yourself to this? Is this really the environment you were made for? To be provoked by nasty emails and an endless parade of workplace problems? Our adrenal glands can handle only so much before they become exhausted. Shouldn’t you preserve them for life-and-death situations?

So yes, use Stoicism to manage these difficulties. But don’t forget to ask: Is this really the life I want? Every time you get upset, a little bit of life leaves the body. Are these really the things on which you want to spend that priceless resource? Don’t be afraid to make a change — a big one.
