You can turn a good business into a bad investment if you pay too much for it.

Price kills even great businesses

We tend to assume that buying into something successful is always smart. A popular restaurant, a thriving tech company, a trendy brand—surely these are safe bets? Buffett's point cuts against this instinct: a genuinely good business can become a terrible financial decision the moment you overpay for it. You're not betting against the business itself; you're betting against the price you paid.

This logic extends beyond stock portfolios. It explains why buying a house in an overheated market can trap you in decades of regret, why paying premium prices for freelancers during hype cycles can sink your startup, or why jumping into any crowded investment—crypto, real estate, even education—at peak prices tends to disappoint. The business might deliver exactly what it promises. You'll just need years of flawless returns just to break even.

The uncomfortable truth is that timing and valuation matter more than having picked a winner. A mediocre business bought cheaply often outperforms a great one bought expensively. That's not pessimism about quality—it's just math. The best business in the world isn't a good investment if you overpay for it.
