Here is a detailed explanation of The Law of the Vacuum, one of the foundational laws in Steven Bartlett's The Diary of a CEO.
The Definition
The Law of the Vacuum states: Nature abhors a vacuum. If you do not intentionally fill your life with purpose, direction, and meaningful priorities, something else—usually distraction, other people's agendas, or chaos—will rush in to fill the space.
Bartlett borrows this concept from the physical principle of horror vacui (nature abhors a vacuum), which states that empty space naturally wants to be filled. He applies it to human psychology, time management, and life purpose.
The core message is simple but brutal: If you don't decide how to spend your time, energy, and attention, someone or something else will decide for you.
The Philosophy Behind the Law
Bartlett argues that most people live in a state of what he calls "reactive existence." They wake up, check their phone, respond to emails, react to demands from bosses, partners, clients, and social media, and then go to bed wondering why they feel unfulfilled.
This happens because they have left a vacuum at the center of their life. Without a clear, self-defined purpose or plan, the world rushes in to fill the void with:
· Distractions: Social media algorithms engineered to capture attention.
· Obligations: Other people's priorities disguised as urgencies.
· Comfort: Mindless consumption (TV, junk food, scrolling) that fills time but adds no value.
· Anxiety: When there is no direction, the mind fills the void with worry and overthinking.
The law applies to every domain: time, relationships, business, and even physical space.
How the Vacuum Manifests
Bartlett identifies several areas where the Law of the Vacuum operates most powerfully:
1. Time and Attention
This is the most common manifestation. If you do not schedule your day with intentionality, your time will be filled by:
· Endless meetings that could have been emails.
· Slack messages and emails demanding immediate responses.
· Social media feeds engineered to steal your attention.
· Other people's emergencies that become your emergencies.
Example: You wake up with no plan. You check Instagram "just for a minute." Three hours later, you have consumed content you don't remember, feel worse about yourself, and have accomplished nothing. The vacuum of unstructured morning was filled by an algorithm.
2. Purpose and Identity
If you do not consciously define who you are and what you stand for, the world will define it for you.
· Culture will tell you what success looks like (money, status, luxury).
· Social media will tell you what to care about (outrage, trends, validation).
· Family and peers will tell you what path to take (college, career, marriage on their timeline).
Example: A young person who never asks "What do I actually want?" ends up in a career their parents chose, living in a city they don't like, following a life script they never wrote. The vacuum of self-definition was filled by external expectations.
3. Business and Strategy
In business, if you do not define your mission, target audience, and unique value proposition, the market will fill the vacuum with confusion. Your team will fill it with politics. Competitors will fill it by taking your customers.
Example: A startup with no clear mission statement will see employees drifting toward different goals, arguments over priorities, and a brand that means nothing to anyone. The vacuum of clarity was filled by chaos and misalignment.
4. Relationships
If you do not define your boundaries and what you want in relationships, others will define them for you. Toxic people will fill the vacuum left by your lack of standards.
Example: Someone who never decides "I will not tolerate being spoken to disrespectfully" will find themselves in friendships and partnerships where disrespect becomes the norm. The vacuum of boundaries was filled by mistreatment.
5. Physical Environment
Bartlett extends this to physical space. A messy room, a cluttered desk, or an unorganized digital folder system creates a vacuum that fills with stress, lost time, and mental fog. The energy you waste searching for keys, documents, or a clean workspace is energy stolen from your purpose.
The Mechanism: Why We Leave Vacuums
Bartlett argues that we leave vacuums not because we are lazy, but because of two psychological factors:
1. The Path of Least Resistance
Filling a vacuum with intentionality requires effort, discomfort, and decision-making. It is easier to let things fill passively. Scrolling requires no effort; planning your day requires effort. Reacting to an email requires no thought; setting a strategic priority requires deep thinking. The brain is wired to conserve energy, so it defaults to the passive path—until the vacuum fills with something painful enough to force change.
2. Fear of Choosing Wrong
Many people avoid filling the vacuum because they are afraid of choosing the wrong purpose. They wait for clarity to strike before committing. Bartlett argues this is a trap. A imperfect plan that you execute and iterate on is infinitely better than a perfect plan you never start. Inaction does not create clarity; action does.
How to Apply the Law of the Vacuum
Bartlett offers a practical framework to proactively fill the vacuum before the world does it for you.
Step 1: Conduct a Vacuum Audit
Identify where vacuums exist in your life. Ask:
· Time: What does my default, unplanned time get filled with? (Scrolling? Worrying? Procrastination?)
· Purpose: Do I have a clear answer to "What am I working toward this year?" If not, what has filled that space? (Other people's goals? Cultural expectations?)
· Environment: Is my physical or digital space cluttered? What stress is that creating?
Step 2: Define Your "Intentional Fill"
You must consciously decide what goes into the vacuum. Bartlett emphasizes that this does not mean scheduling every second of your life. It means defining priorities and non-negotiables.
· Time: Block time for your most important priorities before the week begins. If you do not schedule deep work, exercise, and rest, they will not happen.
· Purpose: Write a one-sentence mission for your current season of life. Example: "For the next six months, my priority is building my health and launching my side business." This sentence acts as a filter to reject things that would fill the vacuum with distraction.
· Boundaries: Define what you will and will not tolerate. Communicate it. A vacuum without boundaries will fill with other people's demands.
Step 3: Embrace "Proactive Discomfort"
Filling the vacuum intentionally often feels uncomfortable at first. Saying "no" to a social invitation to work on your goal feels awkward. Waking up early to plan your day feels harder than sleeping in. Bartlett argues that this discomfort is the price of ownership. If you are not willing to tolerate the discomfort of intentionality, you will tolerate the misery of a life filled by others.
Step 4: Create Systems, Not Just Intentions
Intentions alone are weak. The vacuum will always win if you rely on willpower. Bartlett advocates for systems that automatically fill the vacuum:
· Time Blocking: Put your priorities in your calendar as appointments with yourself.
· Environment Design: Remove distractions. If your phone fills the vacuum of downtime, put it in another room. If a cluttered desk fills your space with stress, clean it at the end of each day.
· Accountability: Tell someone your plan. The vacuum of vague intentions is powerful; the vacuum of a commitment made to another person is much smaller.
Examples in Practice
Vacuum Area What Fills It If Unmanaged Intentional Fill
Sunday Morning Endless scrolling, anxiety about the week ahead Planned morning routine (exercise, reading, planning)
Career Path Parents' expectations, following friends, taking the first job offered Defined mission based on strengths and interests
Business Strategy Team politics, feature creep, chasing competitors Clear mission statement and quarterly priorities
Relationship Boundaries Toxic behavior, resentment, burnout Clearly communicated standards and deal-breakers
Free Time Mindless TV, procrastination, fatigue Scheduled hobbies, rest, and learning
The Cost of Ignoring the Law
Bartlett warns that leaving vacuums unmanaged comes with a steep cost:
· Regret: Looking back and realizing years were filled with other people's priorities.
· Burnout: Being constantly reactive to external demands without time for recovery.
· Identity Loss: Not knowing who you are outside of what you do for others.
· Missed Potential: The gap between what you could have achieved and what you actually achieved, filled by distractions.
Summary of the Law
Aspect Explanation
The Core Idea If you do not intentionally fill your life with purpose and priorities, distractions and other people's agendas will fill it for you.
Where It Applies Time, purpose, business strategy, relationships, physical environment.
Why We Leave Vacuums Path of least resistance; fear of choosing the wrong purpose.
The Solution Conduct a vacuum audit, define intentional priorities, embrace proactive discomfort, and build systems to protect your focus.
The Cost of Ignoring Regret, burnout, identity loss, and unfulfilled potential.
Ultimately, The Law of the Vacuum is a call to radical ownership. It forces you to stop asking "Why is my life so chaotic?" and start asking "What vacuum did I leave that allowed this chaos to enter?" The moment you consciously fill your own space—with purpose, boundaries, and intentional action—you stop being a passenger in your own life and take the wheel.
