On Daily Routines, we profile successful leaders, entrepreneurs, artists, executives and athletes to explore their routines, schedules, habits and day in the life.

As the chairman and CEO of Berkshire Hathaway, and one of the most successful investors in the world, with a net worth of over $70 billion, Buffet is a well-known creature of habit. Born, raised and still living in Omaha, Buffet continues to reside in the same house he bought in 1958 for a little over $30,000.

Warren Buffet’s daily routine typically starts at 6.45am, after getting 8 hours of sleep a night. Instead of coffee, tea, or even water, Buffet’s go-to drink first thing in the morning is a can of coke, “If I eat 2700 calories a day, a quarter of that is Coca-Cola. I drink at least five 12-ounce servings. I do it everyday.”

On his way into the office, Buffet also likes to stop by McDonalds to grab breakfast, “When I’m not feeling quite so prosperous, I might go with the $2.61, which is two sausage patties, and then I put them together and pour myself a Coke,” he revealed in the 2017 HBO documentary, Becoming Warren Buffett. “$3.17 is a bacon, egg and cheese biscuit, but the market’s down this morning, so I’ll pass up the $3.17 and go with the $2.95.”

When asked by Fortune to explain his unusual diet, Buffet replied (perhaps jokingly), “I checked the actuarial tables, and the lowest death rate is among six-year olds. So I decided to eat like a six-year old.”

When Buffet arrives to work at the Berkshire Hathaway offices, a majority of his time is spent reading, “I just sit in my office and read all day.” In fact, he estimates that 80 percent of his daily work routine is spent on reading materials ranging from financial statements, journals and business reports, to newspapers and books.

Alice Schroeder, who wrote the 2008 biography on Buffet, The Snowball: Warren Buffett and the Business of Life, described Buffet’s daily work routine in an interview with Seeking Alpha:

He is already pretty well versed on the news by the time he gets in, through the Internet and television. But he still prefers newspapers. He reads the WSJ, NYT, Financial Times, Washington Post, the Omaha World-Herald. He reads some offbeat things like the NY Observer. He reads all sorts of trade press relating to the different businesses that Berkshire runs. American Banker, Oil & Gas Journal, A.M. Best, Furniture Today. There are stacks of reports from the different BRK subsidiary companies on his desk. Throughout his day he grazes through the reading pile.

While teaching an investing class at Columbia Business School, Buffet held up a stack of paper and said, “Read 500 pages like this every day,” in response to a question about how to prepare for success in investment. “That’s how knowledge works. It builds up, like compound interest. All of you can do it, but I guarantee not many of you will do it.”

In an article for the Harvard Business Review, Bill Gates writes this about Buffet’s reading habits:

Warren follows his own advice: When he invests in a company, he likes to read all of its annual reports going back as far as he can. He looks at how the company has progressed and what its strategy is. He investigates thoroughly and acts deliberately—and infrequently.

The Berkshire Hathaway CEO’s methodical and patient decision-making process was also highlighted by Jeff Bezos, “If I make, like, three good decisions a day, that’s enough. Warren Buffett says he’s good if he makes three good decisions a year.”

Buffet is also well-known for fiercely protecting his time and avoids scheduling meetings or appointments in advance. “Keep control of your time. You won’t keep control of your time unless you can say no — you can’t let other people set your agenda in life.” Gates wrote, “one habit of Warren’s that I admire is that he keeps his schedule free of meetings. He’s good at saying no to things. He knows what he likes to do—and what he does, he does unbelievably well.”

When it comes to sleep, Buffet is usually in bed by 10.45pm, “I get quite a bit of sleep. I like to sleep so I will usually sleep eight hours a night.”

I have more fun here than I think any 88-year-old is having, virtually, in the world.
