A Circle of Competence is the set of topic areas that align with a person's expertise.
If the entire world of information were to be expressed in a circle, an individual's Circle of Competence is the small sub-circle that represents their expertise.
Circle of Competence 101
Warren Buffett and Charlie Munger often reference the importance of knowing the boundaries of your circle of competence.
But what is a Circle of Competence and how does it work?
Here's Circle of Competence 101!
A Circle of Competence is the set of topic areas that align with a person's expertise.
If the entire world of information were to be expressed in a circle, an individual's Circle of Competence is the small sub-circle that represents their expertise.
"You don’t have to be an expert on every company...you only have to be able to evaluate companies within your circle of competence. The size of that circle is not very important; knowing its boundaries, however, is vital."
It is built through experience, reading, dedicated study, and effort.
It is dynamic, not static.
It can expand as you deepen your knowledge in new areas. It can contract if you fail to nurture your existing areas of expertise.
(1) Identify what falls within your circle
(2) Identify the boundaries of your circle
(1) is all about figuring out what you know, while (2) is about humbly admitting what you don’t.
In investing?
Berkshire Hathaway provides the classic example of investing success from sticking within the boundaries of your Circle of Competence.
At times, it has led to what might look like big misses, including failing to see the potential and invest in Google and Amazon.
As Munger once said, you can become a consistent winner by “trying to be consistently not stupid, instead of trying to be very intelligent."
The best operators know their core competencies and are honest about their incompetencies.
The visionary CEOs hire field general, execution-focused COOs.
The field general CEOs hire visionary product leaders.
Own your competencies, outsource the rest.
First, identify your circle and its boundaries.
What topics do you know more about than most people?
What topics do others look to you on?
What are you constantly excited by and learning more about?
Build checks into your decision process that pressure test whether you are remaining true to your Circle of Competence.
Consistently sticking to your circle will lead to good long-term outcomes.
Embrace intellectual curiosity!
Is there a new topic you are excited about? Read everything you can get your hands on.
We live in an unprecedented era of access to information.
You can seek out thought leaders, ask them questions, read their articles, listen to them speak.
It is truly remarkable. Take advantage!
You may just find that your Circle of Competence begins to grow.

1/ An Allegory of Finance
— Sahil Bloom (@SahilBloom) July 18, 2020
I have been posting a lot of educational (and humorous!) threads on finance, money, and economics.
My mission is simple: to demystify these concepts and make them accessible to everyone.
All of the threads can be found below. Enjoy and please share!

From a young age, we are taught to view the world as black and white.
But many of life’s most important truths appear contradictory on the surface.
THREAD: 15 powerful paradoxes (on growth, business, careers, and life):
Sprezzatura (“Studied Carelessness”)
You have to put in more effort to make something appear effortless.
Effortless, elegant performances are often the result of a large volume of effortful, gritty practice.
Simple is not simple.
Slow Down to Speed Up
Want to speed up? Try slowing down.
Slowing down gives you the time to be deliberate with your actions.
You can focus, gather energy, and deploy your resources more efficiently.
It allows you to focus on leverage and ROI.
Move slow to move fast.
Learn More to Know Less
The wisdom paradox - the more you learn, the more you are exposed to the immense unknown.
This should be empowering, not frightening.
“The more I learn, the more I realize how much I don't know.” - Albert Einstein
Embrace lifelong learning.
Shrink to Grow
Growth is never linear.
In order to grow, sometimes you need to shrink.
Shedding deadweight may feel like a step back, but it is a necessity for long-term growth.
This principle applies to your career, startup, or life.
One step back for two steps forward.

I just finished Eric Adler's The Battle of the Classics, and wanted to say something about Joel Christiansen's review linked below. I am not sure what motivates the review (I speculate a bit below), but it gives a very misleading impression of the book. 1/x
The meat of the criticism is that the history Adler gives is insufficiently critical. Adler describes a few figures who had a great influence on how the modern US university was formed. It's certainly critical: it focuses on the social Darwinism of these figures. 2/x
Other insinuations and suggestions in the review seem wildly off the mark, distorted, or inappropriate-- for example, that the book is clickbaity (it is scholarly) or conservative (hardly) or connected to the events at the Capitol (give me a break). 3/x
The core question: in what sense is classics inherently racist? Classics is old. On Adler's account, it begins in ancient Rome and is revived in the Renaissance. Slavery (Christiansen's primary concern) is also very old. Let's say classics is an education for slaveowners. 4/x
It's worth remembering that literacy itself is elite throughout most of this history. Literacy is, then, also the education of slaveowners. We can honor oral and musical traditions without denying that literacy is, generally, good. 5/x
As someone\u2019s who\u2019s read the book, this review strikes me as tremendously unfair. It mostly faults Adler for not writing the book the reviewer wishes he had! https://t.co/pqpt5Ziivj
