Bezos putters, Buffett starts late, and Gates gave up all-nighters. What the richest say about their mornings, and the free parts to copy.
This in-depth guide covers everything you need to know about billionaire morning routine: how the rich sleep and start. Based on verified income data and real-world case studies from our database of 138 side hustle tactics.
The billionaire morning routine you see on social media, the 4 a.m. alarm and the ice bath before dawn, is mostly myth. In their own words, Jeff Bezos and Warren Buffett both say they sleep about eight hours, Bill Gates says seven, and Elon Musk says about six. What the richest people share is a protected first stretch of the day and a rule about when the hard thinking happens, and you can copy both for free.
The 4 a.m. myth meets the people it is about
Picture the billionaire morning that gets shared most. The alarm goes off in the dark. A cold plunge, a green drink, a journal, a run, and four hours of deep work before anyone else is awake. The message is that you could have their life if you got up earlier.
One of the richest men alive starts his day by moving slowly around the kitchen. Another sleeps eight hours and says he has no desire to get to work at four in the morning. A third spent years pulling all-nighters and later wrote that they took a big toll.
So which version do you believe? Below, each claim links to where the person said it, with the year, because habits change. Where a popular claim has no source we could find, we say so.
Jeff Bezos: eight hours, puttering and a 10 a.m. first meeting
Bezos is the clearest example of a slow morning at the very top. At the Economic Club of Washington, D.C. in 2018, he described it in detail, as CNBC reported from the talk's inclusion in the book "Invent & Wander":
"I get up early. I go to bed early. I like to read the newspaper. I like to have coffee. I like to have breakfast with my kids before they got to school," he said. "So my puttering time is very important to me."
He tied that slow start to the timing of his work. "That's why I set my first meeting for ten o'clock," he said in the same talk. He likes to hold his "high-IQ meetings" before lunch, because by 5 p.m. he has had enough of a hard problem for the day and would rather try it again at 10 the next morning.
Sleep is the other half. In a Thrive Global questionnaire, Bezos said: "Eight hours of sleep makes a big difference for me, and I try hard to make that a priority. For me, that's the needed amount to feel energized and excited." He framed it as a business choice. "Making a small number of key decisions well is more important than making a large number of decisions," he said, adding that if you shortchange your sleep, the extra "productive" hours "might be an illusion."
Has the routine survived the years since he stepped back as Amazon's CEO? In a December 2023 conversation on the Lex Fridman Podcast, he described almost the same morning. "I get up in the morning and I putter. I have a coffee," he said, and when asked to define putter: "I slowly move around." He reads his phone and newspapers, chats with his partner, and drinks his first coffee. "So I move pretty slowly in the first couple of hours. I get up early just naturally, and then I exercise most days." He summed it up as "Puttering, coffee, gym, and then work."
The valuable part is the 10 a.m. calendar, which is a habit of saying no.
Tim Cook: the famous early riser
If anyone fits the 4 a.m. stereotype, it is Tim Cook. CNBC reported in 2017 that the Apple chief usually gets up at 3:45 a.m., and that he once took to Twitter to point out that he had woken at 4:30.
His more recent account is a little later. On the BBC podcast "Dua Lipa: At Your Service" in late 2023, Cook said he rises between four and five in the morning and checks email first, according to TechRadar's write-up of the episode. He told Lipa he reads messages from customers and employees as a way to stay grounded, then heads to the gym, where he said he does not check his phone, Business Today reported.
In April 2026, Apple announced that Cook would become executive chairman and that John Ternus would become CEO effective September 1, 2026.
We found no recent quote from Cook about how many hours he sleeps, so we will not guess. An early wake time only tells you when the day starts. Would a 4 a.m. alarm help you, or would it simply move your tiredness to 3 p.m.?
Elon Musk: six hours and the cost of going lower
Musk is often held up as proof that you can sleep less. His own words point the other way.
In a February 2021 appearance on "The Joe Rogan Experience," Musk said he gets "about six hours" of sleep, as CNBC reported. "I tried sleeping less, but then total productivity decreases," he said. He also described late nights: "Normally, I'll be in meetings at work until 1 or 2 in the morning."
The same CNBC piece recalls the period when he said he worked 120 hour weeks during the Tesla Model 3 production push. He told Axios in 2018 that this was "not recommended for anyone."
By May 2023, he was more blunt in an interview with CNBC's David Faber. He makes an effort to sleep at least six hours a night, CNBC reported. "I've tried [to sleep] less, but ... even though I'm awake more hours, I get less done," Musk said. "And the brain pain level is bad if I get less than six hours." In that interview he also said he works seven days a week and takes only "two or three" days a year fully off, and that he does not expect his employees to do the same.
You will often read that Musk plans his day in five minute blocks. We could not find that in his own words or a primary interview, so treat it as unconfirmed.
Bill Gates: from all-nighters to seven hours and Think Weeks
Gates is the convert. In his early Microsoft years, he wrote on his blog, "I routinely pulled all-nighters when we had to deliver a piece of software," CNBC reported in 2019. He sensed he was less sharp on little sleep, "but I was obsessed with my work, and I felt that sleeping a lot was lazy."
Reading Matthew Walker's book "Why We Sleep" changed his view. "I realize that my all-nighters, combined with almost never getting eight hours of sleep, took a big toll," he wrote. By 64, Gates said he needed a full seven hours to feel creative and happy the next day, and he wrote that people "almost certainly" need seven to eight hours a night, according to CNBC. The same report lists the tips from the book that he passed on: no LED bulbs in the bedroom, a cool room of about 65 degrees Fahrenheit (about 18 C), no alcohol to fall asleep, and a short nap before 3 p.m.
His other famous habit sits outside the daily schedule. As Microsoft's boss, Gates took a "Think Week" twice a year, going alone to a cabin in the Pacific Northwest to read papers from Microsoft staff, CNBC reported, citing The Wall Street Journal. During those weeks he sometimes read 18 hours a day. Ironically, the man who now preaches seven hours of sleep used his thinking retreat to stay up into the small hours.
Few of us can take a week alone in a cabin. Could you find one quiet half day a quarter instead?
Warren Buffett: eight hours, a late start and a day of reading
Buffett is the anti-hustle billionaire. In a 2017 PBS NewsHour interview, quoted by CNBC, he said: "I have no desire to get to work at four in the morning." And on sleep: "I get quite a bit of sleep. I like to sleep. So I will usually sleep eight hours a night."
Fortune reported in 2023 that Buffett has said he wakes at 6:45 a.m., reads the news, and sometimes reaches the office after the market has opened. The same piece quotes a 1996 description by his friend Bill Gates: "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 likes to sit in his office and read and think."
That is the whole method. Buffett does not run his day on a timer. He protects long empty stretches for reading, and his morning simply leads into them. Reading as a money habit, including the famous claims about how many pages he reads, belongs to our post on the habits of rich people. Buffett's diet, which Fortune describes as McDonald's, Dairy Queen and Coke, gets its own treatment in what billionaires eat.
Jack Dorsey, Mark Cuban and the others
Jack Dorsey. On Ben Greenfield's podcast in 2019, the Twitter and Square co-founder described a routine built around walking and meditation. TheWrap summarised it in April 2019: he walked the five miles from home to Twitter's office three times a week, in about 75 minutes at a brisk pace, and meditated for at least 10 minutes a session, aiming for up to an hour in the morning and an hour in the evening. He also did short seven minute workouts through the day. His eating, one meal a day, falls under what billionaires eat.
Mark Cuban. In a 2020 Q&A, Cuban said that most nights he gets "about 7 hrs [of sleep]. Less on others," and takes "Dad naps on weekends when I can," CNBC reported.
Mark Zuckerberg and Richard Branson. They sit at opposite ends. In the early days of Facebook, Zuckerberg got to the office around 10:30 a.m. and said in a Facebook Q&A, "I was never a morning person," while Branson says he wakes at 5 a.m. wherever he is in the world, according to the same 2017 CNBC roundup.
Which of these sounds like your natural rhythm? Most people can tell within a second.
Wake time, sleep and first work: the billionaire morning routine table
Each row uses the person's own words where we have them, with the year.

| Mark Cuban | Not stated | About seven hours, plus weekend naps | Not stated | CNBC, 2020 |
Look down the sleep column. So, how many hours do billionaires sleep? Of the people who have said a number, the range is six to eight hours, and Buffett and Bezos sit at the top of it. The wake times spread across three hours. The one pattern that repeats is a decision about when the hard thinking happens.
What sleep research says about these routines
Those are anecdotes from a handful of unusual people. Is there a sleep or wake time that works for everyone?
How much sleep adults need
In 2015 the American Academy of Sleep Medicine and the Sleep Research Society published a joint recommendation that adults get seven or more hours of sleep per night. Their consensus panel found that "sleeping six or fewer hours per night is inadequate to sustain health and safety in adults." They set no upper limit, and noted that more than nine hours can suit young adults, people recovering from sleep debt and people who are ill.
By that standard, Bezos, Buffett, Gates and Cuban sit inside the healthy range, and Musk's six hours falls in the range the panel called inadequate.
Why six hours feels fine when it is not
The most useful study here is a 2003 lab experiment from the University of Pennsylvania. Researchers studied 48 healthy adults. Most were limited to 4, 6 or 8 hours in bed a night for 14 days, and a comparison group went three nights with no sleep at all. People limited to six hours or less built up thinking and attention deficits equal to up to two nights of total sleep deprivation. Their own sleepiness ratings rose at first and then crept up only slightly, and the authors concluded they were largely unaware of how impaired they had become.
Musk said he gets "less done" below six hours. The study suggests that even at six, most people lose more than they can feel.
Too little and too much
A 2010 meta-analysis pooled 16 studies covering about 1.38 million people. Both short and long habitual sleep were linked to a higher risk of death, with long sleep showing the stronger link. These are observational studies, so long sleep may be a sign of illness rather than a cause of it. The practical reading is that the middle of the range, roughly seven to eight hours for most adults, is the safe target.
Morning person or night owl is partly in your genes
A 2019 study of 697,828 people from UK Biobank and 23andMe found 351 genetic regions linked to being a morning person. The size of the effect is modest. In a subgroup of 85,760 people who wore activity monitors, the 5% carrying the most "morningness" variants had a mean sleep timing 25 minutes earlier than the 5% carrying the fewest. The same study found that being a morning person was linked to better mental health, but had no effect on body weight or type 2 diabetes risk.
So Cook at 4 a.m. and Zuckerberg at 10:30 a.m. may both be following their wiring. Forcing an owl into a lark's alarm can cost sleep without giving anything back.
The rare true short sleeper
Some people do need less sleep. A 2009 study in Science linked a mutation in the DEC2 gene to a human short sleep pattern, and mice engineered to carry it slept less than normal mice. That is one specific mutation, so nobody should assume they carry it. If you need an alarm and an afternoon coffee, you are very likely not a natural short sleeper.
Morning routine myths
- "Successful people wake at 4 a.m." Bezos rises early but slowly, Buffett at about 6:45, Zuckerberg was never a morning person. Wake time varies widely, and genes shape part of it.
- "Billionaires sleep four or five hours." None of the people above said so in their own words. The lowest number we found was Musk's six, and he described going lower as painful.
- Five minute time blocks for Musk. We found no primary source, so we left it out of the table.
- Sleeping less to get ahead. The Penn study suggests six hours or less steadily erodes performance while you feel fine. Gates and Musk both describe learning this the hard way.
- Copying the gear. Smart mattresses, trackers and cooling pads get their own post on the billionaire sleep stack. None of the routines above depends on them.
On supplements and sleep aids, the rich take plenty, and our roundup of what supplements billionaires take covers the common ones. If you have trouble sleeping most nights, talk to your doctor before reaching for pills, whether prescription or over the counter. The FDA warns that all drugs taken for insomnia can impair driving and other tasks that need alertness the morning after use, and the American College of Physicians recommends cognitive behavioral therapy for insomnia as the first treatment for chronic insomnia in adults. Loud snoring, gasping at night or heavy daytime sleepiness are reasons to get checked for sleep apnea.
The price of a billionaire morning, and yours
The core of these routines costs almost nothing.
| Habit | Their version | Your version | Rough cost |
|---|
| Eight hours of sleep | Bezos and Buffett, by their own account | A fixed bedtime, counted back from your alarm | Free |
| A slow first hour | Bezos puttering with coffee and the paper | Phone in another room, coffee, 30 quiet minutes | Free |
| Hard thinking before lunch | Bezos's 10 a.m. "high-IQ" meetings | Block your hardest task for your best two hours | Free |
| Long reading time | Buffett's meeting-free days | 30 to 60 minutes of reading on most days | Library card, free |
| Think Week | Gates alone in a cabin, twice a year | One offline half day each quarter | Free, plus a bus fare or a café coffee |
| Walk to work | Dorsey's five miles | A 20 minute walk before work or at lunch | Free |
| Short naps | Gates's tip, Cuban's weekend naps | 20 minutes before 3 p.m. on a day off | Free |
What money buys the very rich is control over their calendar. Bezos can push a meeting to 10 a.m. because he decides when meetings happen. If your shift starts at 7, his advice becomes this: find the two hours when your head is clearest and guard them for the work that matters most, even if those hours fall on a Saturday.
That is also where the money story comes in. If you are building income on the side, the hours you protect are the ones that compound. Our guide to side hustles after work is built around that limited evening and weekend time, and a boring, automatic plan like index investing means the money keeps working while you sleep your eight hours. When does your best thinking happen, and who currently gets those hours?
Your morning experiment this week
Choose any three and run them for a week.
- Set a bedtime from your wake time. If you must be up at 6:30, aim to be in bed by 10:45 so you get seven to eight hours of actual sleep. That one rule covers the habit that Bezos, Buffett and Gates all describe.
- Cut caffeine six hours before bed. A 2013 study found that 400 mg of caffeine taken six hours before bedtime still disrupted sleep and reduced total sleep time. For a 10:45 bedtime, that means your last coffee by about 4:45 p.m.
- Take a slow first 30 minutes. No email, no news feed. Coffee and breakfast, the Bezos way.
- Move your hardest task to your sharpest hours. For most people that is late morning. Put one demanding task there every day this week.
- Read for 30 minutes. Any book. Buffett's habit scales down well.
- Book one offline half day this month, and treat it like a meeting you cannot move.
On day seven, check how you feel. Did the extra sleep or the earlier alarm leave you sharper? Your answer is your routine. If you want a longer view on what all of this is for, the how much money is enough post is a good next read, and the millionaire mindset post covers the habits of thought that sit behind the schedule.
None of this is medical advice. If you have persistent trouble sleeping, or feel exhausted even after a full night in bed, talk to your doctor.
