The One Thing 2,000 Years of Wisdom Says Will Change Your Life

In partnership with

Good morning Grinder,

Have you ever felt like you’re working so hard yet moving so slowly? Do you wake up with good intentions, only to watch the day get hijacked by pings, errands, interruptions, and everyone else’s priorities? Do you tell yourself that tomorrow will be different, that the motivation will finally arrive, that the plan will finally stick? What if motivation isn’t coming? What if there’s a better lever—older, sturdier, proven across centuries—that quietly builds the life you actually want? What if the people you admire aren’t luckier or smarter, but simply better at doing one thing when it counts? And what if that one thing is available to you right now, without buying anything, without waiting for permission, without changing your personality? What happens to your results when your standards stop being negotiable? What happens to your confidence when your actions no longer depend on your mood? What happens to your peace of mind when you stop chasing intensity and start honoring consistency?

That’s the promise at the heart of a powerful conversation featuring author and Stoic teacher Ryan Holiday: discipline—not willpower theatrics, not viral hacks, but steady, self-directed action—builds the future you want. It’s uncomfortable. It’s also unbelievably liberating. And the best part? It’s teachable. If you’ve ever wondered why some people seem to move through setbacks with calm focus while others get spun out, keep reading. This newsletter distills the most useful ideas so you can apply them today—and watch what happens over the next seven days, seven weeks, and seven months.

The “One Thing” isn’t glamorous—and that’s why it works

We love the idea that greatness requires a lightning bolt. But the track record of high performers tells a quieter story. They don’t wait to feel like it. They show up. They build rhythms that carry them through. They lower their reliance on mood and increase their reliance on standards. They choose what matters in advance and follow through when it’s boring, uncelebrated, or inconvenient. That pattern is discipline. It’s not dramatic, but it is repeatable. It’s not flashy, but it frees you—from distraction, from decision fatigue, from the anxious bargaining that happens when you try to negotiate with yourself every hour of the day.

Discipline is not punishment; it’s an agreement with your future self. It’s deciding to become the kind of person who does what they said they would do, especially when no one is watching. If that sounds rigid, consider the alternative: a life ruled by impulse and reactivity. The paradox is beautiful—constraints create freedom. By deciding once, you avoid deciding a hundred times. By making the hard thing non‑negotiable, you make everything else easier.

Ancient wisdom, modern edge

Ryan Holiday taps into the Stoics—Marcus Aurelius, Seneca, Epictetus—who taught that you control your judgments and your actions, not the weather, the market, or other people’s opinions. They practiced negative visualization to prepare for adversity, journaled to sharpen judgment, and used daily physical practice to train the mind through the body. Two thousand years later, these aren’t museum pieces; they’re user manuals. When a setback lands, the disciplined person asks a better question: What’s within my control right now? When a win arrives, they ask: What routine keeps me grounded tomorrow?

This is practical philosophy. It doesn’t ask you to suppress emotion; it asks you to steer attention. It doesn’t require heroic motivation; it invites reliable habits. It doesn’t insist on 10 out of 10 days; it insists on showing up for 7 out of 10 and letting the average compound.

Discipline beats motivation because it doesn’t vanish when you need it most

Motivation spikes are sugar highs. They can start you, but they rarely sustain you. Discipline is a slow‑burn fuel source. It’s built in the small hours and quiet choices—going to bed so you can protect the morning, putting the phone in another room so you can protect your focus, starting ugly so you can protect the streak. At first, it feels like effort. Then it feels like identity. Eventually, it feels like relief: you’re not negotiating every day from zero.

If you’ve ever felt trapped by inconsistency, try this reframing: motivation is a visitor; discipline is a roommate. Motivation might knock on your door; discipline owns a key. Visitors are nice to have. Roommates shape your life.

What this looks like in real life

The disciplined life isn’t a monastic fantasy. It’s remarkably ordinary. You decide your most important work and show up for it every day, before you do anything that dilutes it. You create a small set of personal rules that eliminate friction: where you sit to work, what you touch first, how long you focus before you check messages. You keep promises to yourself in public and in private. You write things down because memory is slippery and willpower is leaky. You accept that boredom is part of mastery and that discomfort is a teacher, not a stop sign.

Maybe your craft is writing, selling, leading, or training. The particulars change; the pattern doesn’t. The pattern is one brick today, then another tomorrow, and the wall over time. When you miss, you return quickly. When you win, you don’t get drunk on victory. You go to bed on time so you can earn tomorrow. You make peace with doing fewer things better, because you finally understand that focus isn’t about saying yes; it’s about saying no without guilt.

A simple way to start this week

You don’t need a perfect plan to live a disciplined week. You need one clear commitment. Choose a single behavior that, if kept, would make everything else easier. Maybe it’s 45 minutes of deep work after waking, before you open your inbox. Maybe it’s a daily walk without your phone to think and reset. Maybe it’s journaling one page each evening to close the mental tabs. Pick the one that removes the most friction from your days. Define exactly when and where it happens. Treat it like a meeting with someone you respect. Show up even when it’s messy. Especially when it’s messy.

Then, let your environment help you. Put the phone out of reach. Lay out the shoes the night before. Open the document you’ll write in so there is no blank‑page resistance tomorrow. Small setups save you when your brain tries to bargain. And when you inevitably slip, don’t mythologize the slip. Resume. A missed day is a bruise, not a break. The disciplined person is not perfect; they’re consistent.

The compounding you can feel

The first dividends of discipline aren’t applause or promotions; they’re internal. You’ll notice more calm because you’re no longer at the mercy of moods. You’ll notice more confidence because your evidence stack grows: day after day, you do what you said you’d do. You’ll notice more time, because you spend less of it dithering, scrolling, or catastrophizing. Later, the external rewards arrive—better work, stronger relationships, improved health—but by then you’re playing a deeper game. You’re not chasing outcomes; you’re honoring a standard. Ironically, that’s when the outcomes get better.

Decide once, live lighter

Discipline isn’t about becoming a harsher version of yourself. It’s about becoming a truer one—the person who aligns action with values and lets consistency do the quiet compounding. Imagine waking up already knowing the first move of your day. Imagine ending it with the gentle satisfaction that you kept your word. Imagine stacking those days until your life looks less like an emergency and more like a craft.

You don’t have to wait for motivation. Decide what matters. Build the rule that protects it. Keep the promise when no one is watching. The results will take care of themselves.

If this resonated, reply and tell me the single disciplined act you’re committing to this week. I’ll be here next issue with practical tools to make it feel even easier.

Best wishes,

Learn from this investor’s $100m mistake

In 2010, a Grammy-winning artist passed on investing $200K in an emerging real estate disruptor. That stake could be worth $100+ million today.

One year later, another real estate disruptor, Zillow, went public. This time, everyday investors had regrets, missing pre-IPO gains.

Now, a new real estate innovator, Pacaso – founded by a former Zillow exec – is disrupting a $1.3T market. And unlike the others, you can invest in Pacaso as a private company.

Pacaso’s co-ownership model has generated $1B+ in luxury home sales and service fees, earned $110M+ in gross profits to date, and received backing from the same VCs behind Uber, Venmo, and eBay. They even reserved the Nasdaq ticker PCSO.
