Warren Buffett's 3 Top Pieces of Advice for Entrepreneurs

Warren Buffett has been building businesses and investing in them for over seven decades. His track record is unmatched. And while much of his advice is focused on investing, the principles that have guided his success apply just as powerfully to entrepreneurship.

Here are the three pieces of Buffett's advice that I return to most often in my work with entrepreneurs and executives.

1. "Only Buy Something That You'd Be Perfectly Happy to Hold If the Market Closed for Ten Years."

Buffett says this about stocks, but the principle applies directly to business decisions: build for the long term.

Too many entrepreneurs are optimizing for the next quarter, the next funding round, or the next exit. This short-term thinking leads to decisions that look good on paper but erode the foundation of a great business — cutting corners on quality, underinvesting in people, sacrificing culture for growth.

The entrepreneurs who build enduring companies ask a different question: "Would I be proud of this decision in ten years?" If the answer is yes, proceed. If not, reconsider.

Application: Before making a major business decision, ask yourself: "Am I optimizing for today, or for the long term?" The two are often in conflict. Choose the long term.

2. "It Takes 20 Years to Build a Reputation and Five Minutes to Ruin It."

Buffett is obsessed with reputation — his own and that of the companies he invests in. He understands that trust is the ultimate competitive advantage, and that it's extraordinarily fragile.

In the age of social media and instant information, this has never been more true. A single ethical lapse, a poorly handled crisis, or a pattern of broken promises can undo years of relationship-building.

The entrepreneurs I've seen fail most spectacularly weren't undone by bad strategy or poor execution. They were undone by a loss of trust — with customers, employees, investors, or partners.

Application: Make every decision as if it will be reported on the front page of tomorrow's newspaper. If you'd be embarrassed by it, don't do it.

3. "The Most Important Investment You Can Make Is in Yourself."

Buffett has said that the best investment he ever made was in a Dale Carnegie public speaking course he took as a young man. Not because public speaking is the most important skill in business — but because investing in yourself compounds over time in ways that financial investments can't.

Every skill you develop, every book you read, every mentor relationship you cultivate, every experience you seek out — these investments compound. They make you a better thinker, a better leader, a better decision-maker.

And unlike financial assets, no one can take them away from you.

Application: Invest at least as much in your own development as you do in your business. Read widely. Seek out mentors. Hire a coach. Attend programs that challenge your thinking. The return on investment is incalculable.

Buffett's genius isn't just in his ability to pick stocks. It's in his ability to think clearly, act with integrity, and take the long view — in business and in life. These three principles are a masterclass in how to build something that lasts.
