Jeff Bezos is the richest person in history.

According to Bloomberg, the founder and CEO of Amazon, the American e-commerce and cloud computing company, has US$166 billion to his name.

In addition to founding the online retail behemoth, Bezos, 54, also owns The Washington Post and the aerospace and spaceflight services company, Blue Origin.

Amazon also recently became the second US company to join the US$1 trillion valuation club, according to Markets Insider; Apple was the first American company to claim that distinction.

So what does daily life look like for this technology mogul?

How does Jeff Bezos, the richest person alive, spend his billions?

Here’s a look at his daily routine:

Sleep to success ...

Bezos is a big believer in getting enough sleep. He wakes up every morning naturally, without the aid of an alarm clock.

Healthy start to each day

He always begins the day by sharing a healthy breakfast with his wife, novelist MacKenzie Bezos, 48, whom he married in 1993.

No early meetings, thank you

To ensure he can spend quality time with MacKenzie and their four children, he never schedules early morning meetings.

Bezos is famously not big on meetings in general. He is said to meet Amazon investors for only six hours every year.

Food for thought

When he does arrange a meeting, Bezos employs a “two-pizza rule” – he never organises big meetings with lots of people in attendance; two pizzas always should be enough to feed the entire group.

In the past he was reportedly an explosive boss at times, but there are rumours that he has hired an executive coach to “help him tone it down”.

No such thing as a free lunch

In general, he has set a “frugal” tone at Amazon, which does not offer perks such as massages or free lunch at employees.

Bezos has a taste for eating unusual dishes. During a meeting with Woot founder Matt Rutledge, he ordered octopus with potatoes, bacon, green garlic yoghurt and eggs for breakfast.

“When I look at the menu, you’re the thing I don’t understand, the thing I’ve never had,” Bezos said. “I must have the breakfast octopus.”

Catering to his cravings

The entrepreneur is also particularly fond of eating food served by catering trucks.

In 2014, he told Henry Blodget, editor-in-chief of Business Insider, about a hugely popular catering vehicle that served workers while parked outside Amazon’s headquarters in Seattle.

“[My craving] – it’s out of control, actually,” Bezos said.

Never too busy for the washing-up

There is one after-dinner ritual that Bezos always adheres to: he does the washing-up.

“I’m pretty convinced it’s the sexiest thing I do,” he told Blodget.

Keeping up appearances 

It is unclear whether Bezos has a workout routine.

However, photos of him taken at a recent conference elicited comparisons with the beefy The Fast and the Furious film actor Vin Diesel, as commenters noted his muscular appearance.

Amazon now runs several popular original television series, such as The Man in the High Castle – a dystopian alternative history series, set in 1962, after Germany and Japan won the second world war – and Transparent – about the father of a Los Angeles family who turns out to be a trans woman.

However, the Amazon CEO is an avowed Trekkie and even made a surprise cameo in the 2016 film Star Trek Beyond.

Other than watching Star Trek, Bezos has another space-related hobby: gliding about in a submarine looking for old rockets from Nasa space launches.

He often takes his children along for the adventure.

When it’s bedtime, ‘Do not disturb’ 

Bezos is very disciplined and makes sure he gets plenty of rest when it’s time for bed.

He sleeps for eight hours every night
