Stay Calm

"Success—in anything, from fitness to business to investing—comes from discipline and patience, not chasing shortcuts. David Booth, who is a visionary and a great friend, reminds us that staying calm, loving the process, and focusing on what we can control is the real path to lasting results. This book is about building strength the smart way—over time." —Arnold Schwarzenegger, longtime Dimensional shareholder From one of the pioneers of index investing and a founder of factor investing comes a clear, calming, and empowering guide to building true wealth—rooted not in predictions, hacks, or market timing but in the science of how markets actually work. “Uncertainty isn’t something to fear—it’s where possibility lives.” —David Booth For more than 50 years, David Booth has been at the center of a monumental transformation in personal finance. As founder of Dimensional Fund Advisors, Booth has worked alongside Nobel laureates Gene Fama, Merton Miller, Myron Scholes, and Robert Merton, helping to transform investing from a game of speculation into a discipline grounded in evidence, diversification, and long-term thinking. In Stay Calm, he shares the lessons, mindset, and stories behind that revolution—and shows readers how to apply them in their own lives. In this accessible and engaging book, Booth explains why trying to pick stocks or predict the market’s next move is a losing game, and why trusting markets—not gurus—gives ordinary investors a powerful advantage.
