The filing cabinet of knowledge stored in Warren Buffett’s brain has helped make him the most successful investor of our time. But it takes much more than simply reading a lot. In this article, learn how to create your own “snowball effect” to compound what you know into opportunity.

Alice Schroeder, the author of Warren Buffett’s authorized biography The Snowball, tells the story of getting into Buffet’s thinking in this informative talk. In her words,
Starting [at a young age] he’s read everything that he could find about business. The subject that interests him, he’s read newspapers, biographies, trade press. He went over to his grandfather who was a grocer and he read the progressive grocer magazine, and he read articles on how to stock a meat department. He’s gone to visit every company that he could find that was even slightly interesting to him, he went down to visit a barrel maker and spent hours talking about how to make barrels. He went to American Express, and he spent hours talking about that business, he went to GEICO and learned about the insurance business. He has stacks of reports on his desk from the companies he owns, pig stalls, jewelry, boat winches, everything you can imagine. He reads hundreds of annual reports every year from companies that he doesn’t own yet, because he just wants to understand their businesses, and then when the opportunity arises, then he’s ready and he can make a decision. What he’s really done is he’s created this immense vertical filing cabinet in his brain of layers and layers and layers of files of information that he can draw back on now for more than 70 years worth of data.
Expiring Information
A lot of us are on the treadmill of consuming expiring information. Not Buffett. He filled his mental filing cabinet with information that had a long half-life.
While most of us focus on consuming information that we won’t care about next month, let alone next year, Buffett focused on knowledge and companies that change very, very slowly or not at all. And because the information he was learning changed slowly he could compound his knowledge over time. And as Schroeder notes, Buffett has been in business for a long time, giving him incredible opportunities to create a cumulative base of knowledge.
Expiring information is sexy but it’s not knowledge. Here are a few telltale signs you’re dealing with expiring information. First, it’s marketed to you. Second, lacking details and nuance, it’s easily digestible. This is why it’s commonly telling you what happened, not why it happened or under what conditions it might happen again. Third, it won’t be relevant in a month or a year. Expiring information is one reason I stopped reading most news. It’s a false map.
But there is another subtle difference to Buffett’s approach that often goes unnoticed…
