Warren Buffett vs Bill Gates Routine (2026): Two Readers, Two Different Systems

Two men famous for thinking for a living, both ending up with a protected night and a protected block of quiet — by opposite routes. One never believed the grind story. The other believed it loudly for decades, then reversed in public. That is the axis here: how each protects thinking time, and what each got wrong about sleep.

Buffett never bought it

Judy Woodruff asked him on PBS NewsHour, broadcast 27 June 2017, "How much sleep do you get?" He said: "I get quite a bit of sleep. I like to sleep. So I will usually sleep eight hours a night, and that -- no, I have no desire to get to work at 4:00 in the morning." We read that transcript on the PBS site; the four-in-the-morning line was unprompted.

The calendar matches. Gates, on seeing Buffett's, in a 2017 conversation with Charlie Rose: "[I] remember Warren showing me his calendar ... he [still] has days that there's nothing on it." That reaches us through CNBC (24 May 2024), brackets and ellipsis theirs; we did not hear the Rose tape, so treat it as reported. Buffett's way of protecting thinking time is subtraction — no protocol, and the block is what is left when nothing gets put in.

One correction carried over from his own page: "500 pages a day" is neither his line nor a day. It is Todd Combs's recollection of a 2001 class, and Combs corrected it himself in May 2023 — "A week ... 500 a day is a little over the top." Roughly seventy pages a day.

Gates bought it, then said he was wrong

He has documented the reversal himself, twice. In a book review published 10 December 2019 on Matthew Walker's Why We Sleep, he describes his Microsoft-era all-nighters and ends the paragraph "... I was obsessed with my work, and I felt that sleeping a lot was lazy." The next sentence turns: "Now that I've read Matthew Walker's Why We Sleep, I realize that my all-nighters, combined with almost never getting eight hours of sleep, took a big toll."

The second is sharper, because he names the competition he was in. Episode 1 of his podcast Unconfuse Me, aired 27 July 2023: "in my thirties and forties, when there'd be a conversation about sleep ... it would be like, 'I only sleep six hours.' And the other guy says, 'I only sleep five!' ... I'd be like, 'Wow, those guys are so good, I need to try harder, because sleep is laziness and unnecessary.'" Then: "So I've swung all the way to looking at my daily sleep scores." Those words reach us through the outlets that covered the episode — CNBC, Fortune, Entrepreneur and Business Today all reproduce the same wording — not from Gates Notes itself, which returns 403 to us. One flag: several outlets state Gates now sleeps a minimum of seven hours. That figure is the reporter's, not his — the transcript never says it. Reported, not verified.

Both clear the floor

Here is the part the genre finds unbelievable. The adult recommendation is seven or more hours a night, from a panel convened by the American Academy of Sleep Medicine and the Sleep Research Society (Watson et al., SLEEP, 2015) — mostly observational evidence, not one experiment. Buffett's eight clears it. So does Gates's stated target, from that same 2019 post: "Does everyone really need seven or eight hours of sleep a night? The answer is that you almost certainly do, even if you've convinced yourself otherwise." Neither is a brag about a short night, and the Gates of thirty years ago would have lost that competition on purpose.

Gates's half has better evidence under it. He watches a daily score, and a meta-analysis of 122 studies found interventions prompting self-monitoring outperformed those without it (Michie et al., Health Psychology, 2009). Nobody has trialled an empty calendar against a full one, so Buffett's side leans on plain repetition: Lally et al. (2010), 96 volunteers, a 66-day median to automaticity — over the 39 whose curves the model fitted, self-reported.

Almost none of the rest is copyable. Buffett empties his calendar because nobody above him fills it; Gates has staff whose job is his schedule. Their thinking time is not a discipline you lack, it is authority over a diary. And both sleeping normally while being successful is two facts side by side, not a chain — thousands do the same, unnoticed.

Pick your branch, and do one thing this week

If your calendar is full and you think that is what serious looks like — take the Buffett branch. Delete or decline one recurring meeting this week, and put a named 60-minute block in the hole it leaves. Name it after what you will actually do in it.

If you are still quietly proud of short nights — take the Gates branch. Count back seven hours from when you have to be up, and set that lights-out as a recurring alarm tonight. Wake at 6:30, it goes in at 11:30pm. Hold it a fortnight, writing down the hour you actually turned the light off — the writing-down is the part with 122 studies behind it.

Educational content, not medical advice, and nothing here is financial advice. Sourcing: Buffett, PBS NewsHour transcript, 27 June 2017. Gates, his 10 December 2019 post and the official Unconfuse Me episode 1 transcript (27 July 2023), both read in full. The calendar quote is reported by CNBC (24 May 2024), not read at source. Persistent sleep trouble deserves a doctor.
