"Index investing beats 85 percent of actively managed mutual funds."
Bryce Leung co-authored Quit Like a Millionaire with his wife, Kristy Shen. After Shen retired from a six-figure engineering career in her early thirties, the couple documented their path to financial independence on their blog Millennial Revolution, then expanded it into a book that combines index-fund investing, aggressive saving, and a skeptical take on conventional career advice into a practical roadmap for early retirement.

Key Ideas & Recurring Themes
Spend on Experiences, Not Stuff
The couple's own data and behavioral research agree: owning less and spending more on experiences like travel correlates with greater happiness and lower stress than accumulating possessions.
The Rule of 72
A simple mental-math shortcut — divide 72 by your expected annual return — estimates how many years it will take an investment to double, making compound growth tangible for everyday planning.
Skip the Advisor, Buy the Index
Leung and Shen make the case that low-cost index funds outperform the large majority of actively managed funds over time, making DIY index investing both simpler and more effective than paying for stock-picking advice.

"Here's how it works: divide 72 by your rate of return to find out how many years it'll take for your money to double. That balance goes up over time, because the money you make makes more money, which in turn makes even more money."— Quit Like a Millionaire
