Bill Gates just dropped his holiday reading list, and it's the kind of eclectic mix that reminds you why the guy stays curious. From octopuses offering life lessons to America's infrastructure problem, these five books tackle big questions without getting preachy about it.

What's on Gates' Winter Reading List

First up is Shelby Van Pelt's Remarkably Bright Creatures, a novel about Tova, a 70-year-old woman who finds unexpected purpose caring for an octopus. According to GatesNote, Gates found it thought-provoking about what comes after your working years end. "I loved this terrific novel about Tova… it made me think about the challenge of filling the days after you stop working," he noted.

For the climate-conscious, Hannah Ritchie's Clearing the Air tackles 50 tough questions about nuclear safety, renewable energy costs, and whether we're actually making progress. Gates appreciates her approach: "She's realistic about the risks but grounded in data that shows real progress," pointing to genuine advances in solar, wind, and electric vehicles.

Barry Diller's memoir Who Knew chronicles his journey from revolutionizing TV movies to launching Fox and building an internet empire. The pattern? Betting on ideas before they became obvious. "He's spent his life betting on ideas before they were obvious," Gates observed.

Steven Pinker's When Everyone Knows That Everyone Knows dives into how humans actually communicate and coordinate socially. Despite tackling complex territory, it's surprisingly accessible. "Although the topic itself is pretty complicated, the book is readable and practical, and it made me see everyday social interactions in a new light," according to the recommendation.

Rounding out the list, Ezra Klein and Derek Thompson's Abundance examines why America struggles to build infrastructure and innovate at scale anymore. Their thesis? "Progress depends not just on good ideas but on the systems that help ideas spread." They push readers to think about rebuilding America's capacity for major achievements.

The Billionaire Reading Habit

Gates isn't alone in his book obsession. The late Charlie Munger, Berkshire Hathaway's legendary vice-chair, famously said success belonged to "learning machines" who grew wiser daily. He marveled at Warren Buffett's habit of reading 500 pages every single day.

The data backs up their enthusiasm. Studies show people who read seven or more business books annually earn 2.3 times more than those who barely crack a spine. Research in The Rich Habits found 85% of self-made millionaires read multiple books monthly.

The pattern repeats across billionaires: Gates himself reads roughly 50 books yearly. Mark Cuban reads broadly from any source he can find. Elon Musk started reading voraciously as a teenager searching for life's meaning, with Hitchhiker's Guide to the Galaxy leaving a lasting impression.

Maybe there's something to this reading thing after all.
