• Time is the most powerful force in investing. Starting early and staying invested are key to building wealth across generations.

On December 31, 2025, legendary investor Warren Buffett retired as CEO of Berkshire Hathaway at age 95. Berkshire Hathaway compounded shareholder capital at approximately 20% annually for over six decades—one of the most remarkable investment records ever achieved. Buffett’s retirement marks the end of one of the greatest investing careers. Yet, the principles that guided him remain just as relevant today for families aiming to grow and preserve wealth across generations.

Sixty years ago, Buffett took over Berkshire Hathaway, a struggling New England textile company, and turned it into a powerhouse that operates everything from insurance firms to household names like Duracell batteries. Along the way, he earned the nickname “Oracle of Omaha” for carefully selecting undervalued companies and holding onto them for the long term—a strategy that has worked well for him. Today, he is the sixth richest person in the world, with a net worth around $154 billion.

Throughout his career, Buffett has shared some of his success secrets, often through his well-known—and often humorous—shareholder letters. Below are some of our favorite insights that continue to guide investors of all kinds.

Navigating Fear and Greed

Investing is carried out by people, and people are emotional. As a result, human behavior heavily influences market movements. Fear and greed can cause investors to jump in and out of the market en masse, often to their own detriment.

Buffett illustrated this idea well when he wrote:

“Occasional outbreaks of those two super-contagious diseases, fear and greed, will forever occur in the investment community…We never try to anticipate the arrival or departure of either disease. Our goal is more modest: we simply attempt to be fearful when others are greedy and to be greedy only when others are fearful.”

Buffett warns us to be cautious when investors are “greedy,” as this can push prices to levels that are not sustainable—sometimes leading to a crash.

Conversely, when investors are fearful, they might miss out on significant opportunities to buy bargains during a market downturn.

The key to successful investing is managing emotional impulses. Buffett has said: “The most important quality for an investor is temperament, not intellect. You need a temperament that neither derives great pleasure from being with the crowd or against the crowd.”

This is one of the reasons we build portfolios that can weather market volatility before it happens, rather than reacting emotionally once it does.

Bursting Bubbles

During market bubbles—such as the Dot Com bubble of the late 1990s or the housing boom leading up to the 2008 crash—prices rise rapidly beyond their true value, fueled by speculation and hype.

Even investors who were initially skeptical may give in to the temptation to join in, entering the market when prices are excessively inflated and due for a crash.

Buffett summarizes this well when he said:

“Bubbles blown large enough inevitably pop. And then the old proverb is confirmed once again: ‘What the wise man does in the beginning, the fool does in the end.’”

Buffett has also said, “It’s only when the tide goes out that you learn who’s been swimming naked.” Indeed, when a booming market turns south, you don’t want to be the one who has taken on too much risk and ends up scrambling to get out.

Playing the Long Game

You’ve probably heard us say that investing is a long-term venture. This is also one of Buffett’s core principles: “Our favorite holding period is forever.” He has additionally stated, “Only buy something that you’d be perfectly happy to hold if the market shut down for 10 years.”

The evidence is clear: over the long term, the stock market has traditionally moved higher. For families building multi-generational wealth, committing to long-term holding periods is the best way to navigate the inevitable short-term market fluctuations that accompany the overall upward trend.

Starting Early

 Unsurprisingly, there's a lot of overlap between aphorisms about planting trees and investing. Both require planning and an early start to ensure you reap their benefits.

As Buffett once said:

“Someone’s sitting in the shade today because someone planted a tree a long time ago.”

Similarly, a well-crafted investment plan needs attention and nurturing, supported by disciplined approaches like dollar-cost averaging—the practice of regularly investing a fixed amount regardless of market conditions—and periodic rebalancing. But mostly, wealth and trees simply need time to grow.

In this sense, Buffett’s “secrets” of success have never truly been secrets. They are just simple truths that all investors can follow: stay calm when others panic, resist the hype, invest regularly, and think long term. Even with these principles, it’s not always easy to stay the course—especially when markets become turbulent.
