Diary of a CEO for Beginners: Where to Start in 2025

Published March 9, 2025 — 12 min read — diaryofceo.online

You keep hearing about it. Friends quote it. Clips flood your TikTok. Someone at work mentioned "that Steven Bartlett podcast" for the third time this week. You finally open YouTube or Spotify and see over 400 episodes staring back at you.

Where on earth do you start?

This is the guide I wish existed when I first discovered The Diary of a CEO. Not a ranked list (we have those too), but a genuine roadmap organized by what you actually care about right now. Whether you're going through a breakup, starting a business, or just want to understand why everyone keeps talking about dopamine — there's a perfect entry point for you.

Quick Navigation

What Is Diary of a CEO, Actually?

The Diary of a CEO (often abbreviated DOAC) is a long-form interview podcast hosted by Steven Bartlett, a British-Nigerian entrepreneur who built and sold a social media marketing company called Social Chain before age 27. He's also the youngest-ever investor on BBC's Dragons' Den.

But the podcast isn't really about Steven. It's about his guests — and the quality is remarkable. We're talking Nobel Prize winners, billionaire founders, world-class neuroscientists, Olympic athletes, and cultural icons, all sitting in a black studio having the kind of honest conversation you rarely hear in mainstream media.

Episodes typically run 1.5 hours, though some stretch to 2+. The format is simple: two chairs, no audience, deep questions. Steven has a talent for creating a space where even the most guarded public figures open up in ways they don't elsewhere.

The show now averages 5-10 million views per episode on YouTube alone, making it one of the biggest podcasts globally. But size aside, the reason it resonates is the density of useful information. Most episodes leave you with at least 3-5 concrete things you can apply to your life immediately.

How to Choose Your First Episode

Here's my honest advice: don't start with the most popular episode.

Start with whatever matches your life right now. Going through a tough time mentally? Start with the mental health section below. Trying to figure out your career? Hit the business episodes. Can't sleep? There's literally an episode about that.

The podcast covers five broad territories:

  1. Business, money, and entrepreneurship — Practical frameworks from people who've actually built things
  2. Physical health — Sleep, nutrition, exercise, longevity (backed by science, not bro-science)
  3. Mental health and psychology — Trauma, anxiety, therapy, emotional intelligence
  4. Relationships and human connection — Dating, communication, attachment styles, loneliness
  5. Purpose and philosophy — Meaning, motivation, discipline, how to actually live well

Below, I've organized the best starter episodes into these paths. Pick whichever resonates and go from there.

Path 1: If You Care About Business & Money

This is where DOAC really shines. Steven's background as a founder means he asks the questions other interviewers miss — the operational details, the emotional toll, the specific numbers.

Start Here: Alex Hormozi — How to Build a $100M Business

Business Must-Listen

Hormozi breaks down his "value equation" — a framework for pricing and offer creation that's become gospel in the startup world. He explains why most businesses fail not because of bad products, but because of bad offers. Extremely tactical, zero fluff. If you're starting or running a business, this episode alone is worth more than most MBA courses.

Key takeaway: The value of your offer = (Dream Outcome — Perceived Likelihood of Achievement) — (Time Delay — Effort and Sacrifice).

Then Watch: Gary Vaynerchuk — The Truth About Social Media

Marketing Personal Brand

Love him or hate him, Gary Vee's episode cuts through the noise about what actually works in digital marketing. His argument that "attention is the new currency" is backed by specific platform strategies. Great for anyone building a brand, freelancing, or marketing a product.

Deep Dive: Simon Sinek — Leadership in the Age of AI

Leadership Career

If you manage people or aspire to, this is essential. Sinek's "infinite game" framework reframes business competition entirely. The AI discussion is surprisingly practical — not fear-mongering, but a realistic look at what skills matter now.

Bonus: Steven Bartlett (Solo) — What I Learned Losing Millions

Entrepreneurship Mindset

Steven's solo episodes are underrated. In this one, he talks about investment failures with brutal honesty — the kind of transparency most CEOs would never risk. It's a reality check for anyone who romanticizes entrepreneurship.

Path 2: If You Care About Health & Your Body

DOAC's health episodes are genuinely world-class. Steven brings on leading scientists and doctors — not influencers — and the conversations go deep enough to be useful without requiring a medical degree to follow.

Start Here: Dr. Andrew Huberman — The Science of Optimal Performance

Neuroscience Sleep Must-Listen

Huberman is the king of actionable science. This episode covers morning sunlight exposure, the biology of focus, caffeine timing, and his famous "non-sleep deep rest" protocol. You'll change at least one daily habit after listening.

Start with this if: You want to optimize your energy, focus, and sleep using protocols backed by peer-reviewed research.

Then Watch: Dr. Rangan Chatterjee — The 4 Pillars of Health

Holistic Health Habits

Where Huberman gives you protocols, Chatterjee gives you a philosophy. His four-pillar framework (movement, nutrition, sleep, stress) is beautifully simple. This is the episode to share with someone who's overwhelmed by health advice and doesn't know where to begin.

Deep Dive: Dr. Tim Spector — The Food Revolution

Nutrition Gut Health

Spector's research on the gut microbiome has changed how millions of people think about food. His argument that "there is no universal healthy diet" is liberating. The episode includes specific food recommendations and the science behind fermented foods, fiber diversity, and why calorie counting is largely pointless.

Bonus: Dr. Matthew Walker — Why We Sleep

Sleep

This episode scared people into sleeping more — in the best possible way. Walker presents the evidence on what sleep deprivation does to your brain, immune system, and lifespan. Practical sleep hygiene tips included.

Path 3: If You're Struggling Mentally

This is where DOAC has arguably had its biggest impact. Steven's willingness to discuss his own mental health — and to sit with experts in uncomfortable silence — has produced episodes that listeners describe as "life-changing" without exaggeration.

Start Here: Dr. Paul Conti — Understanding Trauma and the Unconscious Mind

Trauma Psychology Must-Listen

Dr. Conti explains how unprocessed trauma shapes everything from your relationships to your career decisions — often without you realizing it. Steven is visibly moved during parts of this conversation. It's heavy but hopeful: Conti provides a clear framework for understanding and addressing trauma.

Warning: This episode can be emotionally intense. It's worth it, but maybe don't listen on your commute.

Then Watch: Dr. Julie Smith — Why You Feel Lost

Anxiety Self-Help

Dr. Julie Smith became famous on TikTok for explaining complex psychology in simple terms, and she brings that same clarity to this conversation. Covers anxiety management, the "emotional elevator" concept, and practical CBT techniques you can use immediately.

Deep Dive: Gabor Maté — The Root of All Addiction

Addiction Childhood

Dr. Maté's thesis — that addiction is always rooted in childhood pain — is presented with such compassion that it reframes how you think about everyone in your life, including yourself. Whether or not you struggle with addiction, this episode illuminates patterns you've never noticed.

Bonus: Mel Robbins — The Let Them Theory

Boundaries Viral

The clip from this episode surpassed 20 million views. The "Let Them Theory" is simple: stop trying to control other people's behavior and focus on your own response. Robbins delivers it with trademark energy. It's the kind of reframe that sounds obvious but hits differently when you hear the full context.

Path 4: If You Want Better Relationships

DOAC's relationship episodes are genuinely nuanced — no "alpha male" nonsense, no toxic positivity. Just honest conversations about why connection is hard and what actually helps.

Start Here: Matthew Hussey — The Truth About Modern Dating

Dating Communication

Hussey strips away the games and manipulation tactics that dominate dating advice online. His framework for "high-value communication" is practical and applies to all relationships, not just romantic ones. The segment on texting anxiety alone is worth the listen.

Then Watch: Chris Williamson — Why Modern Dating Is Broken

Loneliness Culture

A broader sociological look at why so many people feel disconnected. Williamson and Bartlett discuss dating app culture, the friendship recession, and what happens to a society where people stop forming deep bonds. Thought-provoking rather than prescriptive.

Deep Dive: Jay Shetty — Building Relationships That Last

Long-term Purpose

Shetty's perspective combines his monk training with modern relationship science. His "three phases of love" framework and the "Sunday Reset" routine for couples have been widely adopted by listeners. Less about finding love, more about keeping it alive.

Path 5: Steven's Solo Episodes — The Hidden Gems

Most people discover DOAC through the big-name guests. But Steven's solo episodes — where he sits alone and shares what he's learned — are some of the most honest content on the internet. No performance, no playing host. Just a guy processing his experiences out loud.

Start with the "What I Learned Losing Millions" episode if you're entrepreneurial, or "The Speech That Will Change Your Life" if you need motivation. His solo episode on loneliness is quietly one of the best things he's ever done.

These episodes are typically shorter (30-60 minutes) and make great entry points if you're not ready to commit to a 1.5-hour conversation.

Tips for Getting the Most Out of DOAC

After listening to hundreds of hours of this podcast, here's what I've learned about how to actually use it:

1. Take Notes on One Thing, Not Everything

Each episode contains dozens of insights. You'll retain almost none of them if you try to absorb everything. Instead, listen for one idea that challenges something you currently believe, and write it down. That's your takeaway.

2. Use 1.5x Speed Strategically

Most episodes work fine at 1.25-1.5x speed. But slow down for the emotional episodes — the Gabor Maté and Paul Conti conversations lose their power when sped up. Let those breathe.

3. Start With YouTube, Not Audio

DOAC is filmed beautifully, and a surprising amount of communication happens in body language and facial expressions. Steven's reactions often say as much as the guest's words. Watch the first few episodes before switching to audio-only.

4. Don't Binge — Space It Out

It's tempting to marathon episodes, but the insights land better when you have time to process between them. One episode every 2-3 days gives your brain space to actually integrate what you've heard.

The Episode I'd Personally Recommend First

If you forced me to pick one single episode to start with, regardless of your interests, I'd say: Dr. Rangan Chatterjee — The 4 Pillars of Health.

Why? Because everyone has a body, everyone wants to feel better, and Chatterjee delivers advice so clear and practical that you'll implement at least one change before the episode ends. It's warm, evidence-based, and covers topics that affect every area of your life — sleep, stress, movement, and food. It's also one of the more accessible episodes in length and complexity.

After that, follow whatever thread interests you most. That's the beauty of a catalog this deep — no matter where you are in life, there's an episode that feels like it was made for exactly this moment.
