Somewhere along the way, productivity became synonymous with endurance. Long hours. Back-to-back meetings. The quiet pride of being the last one to log off. But if you’ve ever finished a ten-hour workday and struggled to remember what you actually accomplished, you’ve felt the lie at the heart of that approach.

Your brain is not built for marathons. It’s built for sprints — roughly 90-minute ones, followed by short recovery breaks. Sleep researchers call these ultradian rhythms: the natural cycles of high focus and low focus that run through your day, whether you respect them or not. Ignore them, and you spend your afternoon pushing through molasses. Work with them, and you can do in four hours what your past self struggled to finish in eight.

The Shape of a Real Productive Day

Most productive days don’t look like a flat line of constant effort. They look like a heartbeat — three or four sharp peaks of focus, separated by genuine rest. The peak doesn’t last forever. After about 90 minutes, your prefrontal cortex starts running on fumes. Decisions get harder. Errors creep in. The work you do in the second half of an unbroken three-hour block is almost always worse than what you did in the first 90 minutes.

The fix isn’t more discipline. It’s better punctuation.

How to Build a Sprint-Based Day

1. Pick one thing per sprint.

Before a sprint starts, decide on one outcome — not a category, not a project, but a single deliverable you could realistically finish or meaningfully advance in 90 minutes. “Work on the proposal” is too vague. “Draft the executive summary section” is a sprint.

2. Eliminate the obvious traitors.

Slack, email, your phone, the browser tab you keep “just checking.” These don’t moderately reduce your focus — they shatter it. Research on context-switching suggests it can take 15 to 25 minutes to fully reorient after a single interruption. In a 90-minute sprint, you cannot afford one. Close everything.

3. Actually rest between sprints.

This is where most people fail. They finish a sprint, then “reward” themselves with 15 minutes of doomscrolling, which keeps the same overstimulated brain circuits running. That isn’t rest. Real recovery means moving your body, getting outside, drinking water, or staring out a window. Boring is the goal. Your brain consolidates and resets when it isn’t being fed novelty.

4. Stop at three or four sprints.

Three deep sprints in a day is a great day. Four is exceptional. Five is almost always a lie you’re telling yourself — the work in the fifth sprint is usually so degraded that you’ll redo it tomorrow anyway. Protect the ceiling, and the floor takes care of itself.

The Counterintuitive Part

The hardest thing about working in sprints isn’t the focus — it’s the permission. We’ve been trained to feel guilty about stopping. To equate visible busyness with virtue. To believe that if we’re not at our desk, we’re not working.

But the people who consistently produce remarkable work — writers, surgeons, researchers, founders — almost universally protect their recovery time as fiercely as their focus time. Not because they’re lazy, but because they understand a basic truth most of us resist: the rest is the work. It’s where the next sprint’s quality is built.

Try It Tomorrow

Don’t redesign your whole life. Just try one sprint. Pick one task. Set a timer for 90 minutes. Close everything else. When the timer ends, get up and walk for 15 minutes — no phone. Then notice how you feel.

Most people are surprised twice. First, by how much they got done. Second, by how much energy they have left for the rest of the day.

That’s not a productivity hack. That’s just what working with your brain — instead of against it — actually feels like.

Most productivity advice focuses on what to do. The 3-Block Method is about when to do it — and why the sequence matters as much as the tasks themselves.

The Problem with To-Do Lists

A to-do list tells you what needs doing. It says nothing about your mental state when you attempt it. Writing a complex report at 3pm after back-to-back meetings is very different from writing it at 9am with a clear head. Same task, wildly different outcomes.

The 3-Block Method fixes this by matching your work to your energy, not just your schedule.

Block 1: Deep Work (First 2–3 Hours)

Your brain is freshest in the morning — cognitively speaking, willpower and focused attention peak early in the day for most people. Use this window for your one most important task: the thing that, if done well, makes the rest of the day feel like a success.

Rules for Block 1:

• No email, no Slack, no meetings
• One task only — resist multitasking
• Time-box it: 90 minutes is the sweet spot for deep concentration

This isn’t about heroic discipline. It’s about protecting a window that’s already yours — you just have to stop giving it away to notifications.

Block 2: Collaboration and Communication (Midday)

After your deep work block, your energy naturally shifts. This is the right time for meetings, calls, emails, and collaborative work. You’re alert but no longer in that peak creative state — which is fine, because these tasks don’t require it.

Batch your communication here instead of spreading it across the day. Checking email five times a day is far less disruptive than checking it every 20 minutes.

Block 3: Administrative and Low-Effort Tasks (Afternoon)

Most people hit an energy dip between 2–4pm. Don’t fight it — work with it. This is the time for tasks that require less mental horsepower: filing, reviewing documents, scheduling, light research, or planning tomorrow’s deep work session.

Ending the day with planning is one of the highest-leverage habits you can build. Five minutes reviewing what you accomplished and writing tomorrow’s one most important task means you wake up with direction instead of drift.

Why This Works

The 3-Block Method isn’t a rigid schedule — it’s a framework for intentionality. You’re making one key decision each day: what deserves my best hours?

When you answer that question in advance, you stop reacting to whatever feels most urgent and start investing in what actually matters.

Try It Tomorrow

1. Tonight, write down your single most important task for tomorrow.
2. Block the first 90 minutes of your morning for that task only.
3. Move all meetings to midday or later.
4. Review and repeat.

One week of this practice will tell you more than any productivity book. Give it a try and see what shifts.

Most productivity advice treats your brain like a machine that should run at full speed for eight hours a day. It can’t, and it never has. The good news is that the rhythm it actually runs on is well documented, and once you stop fighting it, you get more done in less time.

Your brain works in waves, not a straight line

In the 1950s, sleep researcher Nathaniel Kleitman noticed that the body cycles through alertness and rest roughly every 90 minutes — not just at night, but throughout the day. He called these ultradian rhythms. During each cycle, you get a window of sharp focus followed by a clear dip in energy. Push through the dip and you don’t get more output; you get sloppier output and a longer recovery later.

Once you start watching for it, the pattern is obvious. You sit down sharp, do your best thinking for 60 to 90 minutes, and then your attention starts drifting toward email, snacks, or your phone. That’s not a willpower failure. That’s your brain asking for a break.

The structure that actually works

Instead of a vague eight-hour workday, try structuring your day around three or four focused 90-minute blocks separated by real recovery breaks. Here is what that looks like in practice:

1. Pick one thing per block. Not a list. One thing. If you can’t say what “done” looks like in a sentence, the block is too vague.
2. Remove the obvious leaks. Phone in another room, notifications off, one browser window. The point is not discipline; it is reducing the number of decisions you have to make.
3. Stop at the 90-minute mark, even if you feel good. This is the counterintuitive part. Stopping while you still have momentum makes it dramatically easier to start the next block.
4. Take a real 15- to 20-minute break. Walk, eat, look out a window. Not a break that involves another screen. Your brain needs to genuinely disengage to recharge.

What to do with the dip

The afternoon slump is not a personal weakness — it’s a predictable trough in the cycle, usually somewhere between 1 and 3 p.m. Most people fight it with caffeine and lose the rest of the day. A better move is to schedule shallow work there on purpose: replying to messages, organizing files, processing receipts. Save your hardest thinking for the high-energy windows in the morning and late afternoon.

The honest tradeoff

Working in 90-minute blocks means you will spend fewer hours “at work” but more hours actually working. For some jobs and some bosses, that visibility tradeoff is real. If you can’t restructure your whole day, start with one block. Pick the most important thing on your list, protect 90 minutes for it tomorrow morning, and see what happens.

Productivity is not about squeezing more out of a tired brain. It is about noticing when your brain is sharp, getting out of its way, and resting it before it forces you to.

Most people treat Monday like a burden — the end of rest, the beginning of obligation. But the most productive people I know treat Monday as a gift: a blank slate, a fresh start, a chance to build momentum before the week builds it for you.

Here are five habits that turn Monday from a wall into a launchpad.

1. Do a Weekly Review on Sunday Night (Yes, the Night Before)

The single biggest productivity unlock is knowing what you’re walking into. Spend 15 minutes Sunday evening scanning last week’s unfinished tasks, checking your calendar for the week ahead, and writing down your top 3 priorities. You’ll sleep better and hit Monday with direction instead of drift.

Try this: Keep a simple “Weekly Intentions” note — just three sentences: what I want to finish, who I need to connect with, and one thing I’ll protect time for.

2. Don’t Check Email First Thing

Email is other people’s agenda wearing your attention like a suit. The first 60–90 minutes of your day are neurologically your sharpest — your prefrontal cortex is fresh, distractions haven’t accumulated, and deep work is actually possible. Handing that window to your inbox is like using a scalpel to cut butter.

Instead, start Monday with your single most important task. Even 45 minutes of uninterrupted focus on what matters most will set a completely different tone for the rest of the day.

3. Time Block, Don’t Just List

A to-do list is a wish. A time block is a commitment.

On Monday morning, open your calendar and physically block time for your three priorities. Assign a start time, an end time, and treat the block like a meeting with yourself. Research from Cal Newport and others consistently shows that people who time block complete significantly more meaningful work than those who work from lists alone.

The magic isn’t the schedule — it’s the decision-making you do upfront. You stop asking “what should I do next?” a hundred times a day.

4. Build a Transition Ritual

Your brain needs a signal that work mode has begun. Without a ritual, you slide into the day without ever fully “arriving.” The most effective ones are short (5–10 minutes), consistent, and sensory: a specific playlist, a cup of coffee made the same way, a short walk, or even writing three sentences about what you want to accomplish.

The content matters less than the consistency. Your brain will start to associate the ritual with focus, and context-switching will get faster and easier over time.

5. Schedule One “Win” Early

Momentum is real, and it compounds. If you complete something meaningful by 10am — even something small — you’ve changed the psychological weather of your entire day. You’ve proven to yourself that you’re capable and in motion, and that feeling carries forward.

Deliberately choose one task Monday morning that you know you can finish. Ship it, check it off, feel the shift. Then go after the harder things.

---

Productivity isn’t about doing more — it’s about doing the right things with the energy and attention you actually have. Monday is the best day to make that decision deliberately. The week is still yours.

What’s your Monday reset routine? I’d love to hear what works for you.

We keep adding things — apps, routines, systems, habits. But what if the move that would actually change everything is subtracting?

There’s a concept in psychology called additive bias. When faced with a problem, humans instinctively look for something to add rather than something to remove. Researchers demonstrated this with a simple Lego test: given an unstable structure, almost nobody thought to take away the block that was causing the problem. They just kept stacking.

Sound familiar? When your week feels chaotic, the instinct is to grab a new task manager, start a morning routine, or try time-blocking. Rarely do we stop and ask the harder question: what should I just stop doing?

Four places to start cutting

01 — Meetings. Audit your recurring ones. A lot of them exist purely out of inertia. If it doesn’t have a clear owner and outcome, cancel it and see if anyone notices.

02 — Notifications. Research puts the average recovery time after an interruption at 23 minutes. You don’t need better notification settings — you need fewer notifications. Turn off everything that isn’t time-critical, full stop.

03 — Half-hearted commitments. Every “sure, I can do that” that you’re not actually excited about is quietly draining you — even when you’re not working on it. Derek Sivers’ rule is worth living by: if it’s not a hell yes, it’s a no.

04 — Repeated low-stakes decisions. What to eat, what to wear, what to start with — these small choices erode the mental energy you actually need. Batch them, automate them, or just decide once and move on.

One thing to try this week: Every Friday before you close your laptop, ask yourself — what’s one thing I’ll stop doing next week? Not add. Stop. One removal per week is 52 in a year. That adds up to a very different life.

The people who do their best work consistently — great writers, founders, athletes — almost all share this habit. They protect their attention fiercely by eliminating everything that doesn’t serve what they’re actually trying to do. Warren Buffett keeps 80% of his calendar empty by design. That’s not laziness. That’s precision.

Productivity isn’t about fitting more in. It’s about seeing clearly what matters — and then protecting the space to actually do it.

Until next week,

Stop Blaming the Arena
One of the biggest traps in life is blaming the circumstances around us.
The arena.
Other people.
The kids.
The timing.
The stress.
But the truth is simple and uncomfortable:
You against you. Only.
The moment you stop blaming the arena is the moment you reclaim your power.

Live Like the Hero of Your Own Story
Imagine your life as a movie.
You are the hero.
If that were true, what would the hero do today?
Not someday. Not when things get easier. Now.
A hero doesn’t wait for perfect conditions. A hero moves forward even when things feel uncertain, uncomfortable, or hard.
This realization changes everything: you are always one decision away from changing your life.

12 Years Sober — And No, This Isn’t a Prank 😄

Twelve years ago, I decided to quit drinking. At first, most of my friends didn’t believe me.
“You? Quit alcohol? Yeah right.”
They thought it was just a phase… until I hit year two and they realized I was actually serious.

Since then, the jokes stopped, and the respect started showing up. Now I’m the designated driver, the one who remembers all the wild stories, and the guy people come to when they’re thinking about cutting back.

Truth is, I’ve never felt better. Sobriety gave me clarity, purpose, and peace I didn’t even know I was missing. I still love to laugh, dance, hang out, and make memories—just without the hangovers and bad decisions.

To anyone thinking they can’t do it: I was you once. If I can do it, so can you.
One day at a time turns into one year… then two… then twelve. 💪

Thanks to everyone who stuck by me and believed in me—eventually. 😂
Here’s to 12 years of living fully, clearly, and with a lot more snacks.
