They do. And more than almost any other habit, reading is the one wealthy people report in common. Tom Corley, who studied the daily habits of wealthy and poor families for five years for his book Rich Habits, found that 88 percent of the wealthy people he tracked read at least 30 minutes per day for self-improvement. Warren Buffett has told college students he spends most of his workday reading, and famously advised them to read 500 pages a day because knowledge “builds up, like compound interest.” Bill Gates reportedly gets through about fifty books a year.
You might be able to dispute any one of these statistics. The overall trend is difficult to deny.
Primarily not for entertainment. The reading wealthy individuals describe is closer to training: biographies, how-to books, history, industry material. A few reasons come up again and again.
Borrowed mistakes are less costly than your own. A book is an individual’s expensive decade condensed down to ten hours. When you learn how a founder botched hiring or how an investor survived a downturn, you receive the lesson without having paid the price.
Compounding applies to knowledge. A page today seems as pointless as a dollar saved today. Both look absurd in isolation and unstoppable over a decade — the same way Darren Hardy describes the impact of daily decisions in The Compound Effect.
Reading is the least expensive mentorship available. The majority of people will never get an hour with a successful operator or investor. Their books cost twenty dollars and contain more than any one hour could.
Buying books changes nothing; neither does finishing them. People who achieve something view reading as an input to action: one idea applied per book beats ten books admired. This is why we include a single action step at the bottom of every review on this site — and why the habit itself matters more than any particular book. If you want to develop the habit first, begin with our Atomic Habits summary.
Start with one book — matched to your current problem. If money habits are the problem, pick from our list of money mindset books. If you’re building something, the best books to build wealth guide organizes the classics by what they each excel at. Read thirty minutes daily, apply one idea per book, and let the compounding continue on its own.
There is no single number — Gates’ roughly fifty a year is the famous figure, and Corley’s data emphasizes daily minutes over annual book counts. The honest answer: the consistent finding is daily reading for self-improvement, not a specific annual total.
Mainly non-fiction: biographies, business, personal development, history. Corley specifically found the wealthy families he studied preferred self-improvement reading over entertainment reading — the opposite of the pattern he recorded among low-income households.
