You’re probably thinking about a dozen things right now. One of them is likely this sentence, but the others are probably a messy mix of that email you forgot to send, what you’re having for dinner, and maybe a weirdly specific memory from 2014. It’s chaotic. That’s the default state for most of us because, honestly, we’ve stopped practicing the art of thought as a deliberate skill. We treat thinking like breathing—something that just happens in the background—rather than a craft that needs sharpening.
Most people assume "thinking" is just the noise in their head. It isn't.
True thought is structured, patient, and increasingly rare in a world that pays us to react rather than reflect. If you feel like your brain is constantly "buffering" or you can’t focus on a single complex problem for more than six minutes, you aren’t broken. You’ve just lost the rhythm.
What Most People Get Wrong About Intellectual Labor
There’s this weird myth that great ideas just "strike" like lightning. We love the story of Archimedes in the bathtub or Newton under the apple tree because it makes the art of thought seem accidental. It’s a nice story. It’s also mostly garbage.
In reality, Graham Wallas, a co-founder of the London School of Economics, broke this down back in 1926. He described a four-stage process: Preparation, Incubation, Illumination, and Verification. Most of us skip the first two and wonder why the third one never happens. We try to force "Illumination" while staring at a blank Google Doc, which is like trying to harvest wheat before you’ve even bought the seeds.
You have to feed the brain. Then, you have to leave it alone.
The "Incubation" phase is where the real art of thought happens. It’s the period where your subconscious takes the raw data you’ve gathered and starts making weird, unexpected connections. This is why you get your best ideas in the shower or while driving. Your conscious mind is finally distracted enough to stop micromanaging your brain. When you’re constantly scrolling through TikTok or checking Slack, you’re essentially blocking the incubation process. You’re giving your brain zero "dark time" to process.
The Cost of Cognitive Switching
Let’s talk about "switching costs." Every time you jump from a deep task to a notification, you pay a tax.
Researchers like Sophie Leroy at the University of Minnesota call this attention residue. When you switch from Task A to Task B, part of your brain stays stuck on Task A. You aren’t actually multitasking; you’re just vibrating between incomplete thoughts. This kills any chance of achieving a high-level art of thought because you’re never fully "present" in any single idea.

It takes roughly 23 minutes to get back into a state of deep focus after an interruption. If you get a text every 15 minutes, you are—mathematically speaking—never actually thinking at full capacity. You’re living in the shallows.
Why Writing is Actually Thinking
You've probably heard the phrase "I don't know what I think until I see what I say."
That’s not just a cute quote; it’s a biological reality for many. Writing is the externalization of thought. When ideas stay in your head, they are slippery. They change shape. They hide their own logical fallacies because the brain is excellent at lying to itself to save energy.
When you put a thought on paper (or a screen), it becomes static. You can look at it. You can see where the logic breaks. This is why keeping a journal or writing long-form essays is one of the most effective ways to master the art of thought. It forces a level of precision that "just thinking" doesn't require.
- It slows you down.
- It exposes gaps in your knowledge.
- It creates a "second brain" you can reference later.
Honestly, if you can’t write it down clearly, you probably don’t understand it as well as you think you do.
The Role of Boredom in Deep Reflection
We are the first generation of humans who never have to be bored. Waiting for a bus? Phone. Standing in line? Phone. Commercial break? Phone.
But boredom is the soil in which the art of thought grows.
When you remove external stimuli, your brain is forced to look inward for entertainment. This is called the Default Mode Network (DMN). The DMN is active when we are daydreaming or mind-wandering. It’s responsible for self-reflection and autobiographical memory. By constantly drowning out boredom with "content," we are effectively starving the DMN. We are losing the ability to wonder.

Think about the last time you just sat and looked out a window for twenty minutes. No music. No podcast. No "productivity." It feels uncomfortable, doesn't it? That discomfort is your brain’s "atrophied muscle" screaming. To reclaim the art of thought, you have to get comfortable with being bored again.
Mental Models: The Tools of the Craft
You can’t build a house with just a hammer. Similarly, you can’t think through complex life problems with just one way of looking at the world.
Expert thinkers use Mental Models. These are essentially internal maps that help us understand how things work. Take "First Principles Thinking," popularized by people like Elon Musk but rooted in Aristotelian philosophy. It involves breaking a problem down to its fundamental truths and building up from there, rather than reasoning by analogy (doing things because "that's how they've always been done").
Then there’s "Inversion." Instead of thinking about how to be successful, think about how to fail miserably—then avoid those things.
Charlie Munger, the late billionaire investor, was a massive proponent of this. He argued that most people try to be brilliant, while the real art of thought is often just consistently avoiding being stupid. It’s a subtle shift, but it changes everything about how you approach a problem. If you want a happy marriage, don't just ask "how can I be a great spouse?" Ask "what would definitely ruin this marriage?" and then stop doing those things.
The Biological Floor: Sleep and Glucose
We like to think of the mind as this ethereal, spiritual thing. It isn't. It’s a biological organ that weighs about three pounds and consumes 20% of your daily calories.
If you aren't sleeping, you aren't thinking. Period.
During sleep, the glymphatic system flushes out metabolic waste—specifically beta-amyloid proteins—that builds up during the day. When you pull an all-nighter or survive on four hours of sleep, you are literally trying to think through a "clogged" brain. Your ability to engage in the art of thought drops to the level of someone who is legally intoxicated.

Similarly, your brain runs on glucose. When your blood sugar crashes, your executive function (the part of the brain that handles complex reasoning) is the first thing to go offline. This is why you shouldn't try to solve your life's biggest problems at 4:00 PM on an empty stomach. You'll just spiral into anxiety because the "primitive" parts of your brain are taking over.
Actionable Steps to Reclaim Your Mind
Improving your thinking isn't about becoming a genius; it's about removing the obstacles you've put in your own way.
Implement a "Low Information Diet"
Stop consuming news or social media that has a half-life of less than 24 hours. If it won't matter in a week, don't let it in. This clears the "noise" and leaves room for the art of thought. You'll find that 90% of what you thought was "essential information" is actually just distraction.
Practice 4-Hour Time Blocks
Deep work requires momentum. Set aside one or two mornings a week where you have zero meetings and zero notifications. It takes time to "warm up" into deep thought. You can't do it in 15-minute increments between Zoom calls.
Talk to People You Disagree With
This is the hardest part. Our brains naturally seek out "confirmation bias"—information that proves we’re already right. To actually think, you have to seek out the strongest version of the opposing argument (often called "steelmanning"). If you can’t argue the other side better than your opponent can, you don't actually understand the issue yet.
Walk Without Tech
Friedrich Nietzsche famously said, "All truly great thoughts are conceived by walking." He wasn't talking about walking on a treadmill while watching Netflix. He meant walking in nature, letting the eyes wander. The rhythmic movement of walking combined with a lack of focused visual input (like a screen) creates the perfect environment for "incubation."
Audit Your Influences
You are the average of the ideas you consume. If you spend all day reading angry tweets, your thoughts will be angry and reactive. If you spend time reading long-form books and historical biographies, your thoughts will naturally become more nuanced and long-term. Choose your "intellectual ancestors" carefully.
The art of thought is a commitment to the long game. It’s the realization that your mind is your most valuable asset, yet it’s the one you’re most likely to neglect in the rush of daily life. By slowing down, embracing boredom, and learning to sit with a single idea for longer than a few seconds, you’re doing something radical. You’re becoming an active participant in your own consciousness rather than just a passenger.
Start by putting the phone in another room for thirty minutes today. Sit with a notebook. See what comes up. It might be uncomfortable at first, but that’s just the sound of your brain starting to work again.
Practical Thinking Frameworks to Try Today:
- The Rule of Three: When faced with a decision, always force yourself to find three viable options. Usually, we get stuck in "A vs B" binary thinking. Finding a third option forces the brain to get creative.
- Second-Order Thinking: Don't just ask "what will happen if I do this?" Ask "and then what?" Look for the consequences of the consequences.
- The Feynman Technique: Try to explain a complex concept you're thinking about to a hypothetical 10-year-old. If you use jargon, you don't understand it. Simplify until the core truth is all that's left.
- Time-Travel Reflection: Ask yourself, "Will I care about this problem in five years? Five months? Five weeks?" This immediately strips away the emotional "heat" of a thought and lets you see the logic underneath.
