Sam Altman, known for his leadership at OpenAI and Y Combinator, often shares insights he’s gleaned from remarkable thinkers. One standout lesson came from Peter Thiel, a legendary entrepreneur and investor. Thiel’s candid reflection on his biggest investment mistake carries a powerful message: hesitation in recognizing and acting on groundbreaking opportunities can cost you dearly.

Peter Thiel’s Unexpected Admission
When asked about his biggest mistake, Thiel didn’t cite a failed investment. Instead, he revealed that his greatest regret was not investing in Facebook’s Series B. This wasn’t about losing money but about missing out on what became one of the most transformative companies of the century. For Thiel, this mistake wasn’t about a lack of resources but a lack of boldness in pursuing a clear winner.
Sam Altman’s Takeaway: Spot the Winners and Double Down
Altman took this lesson to heart. He’s a firm believer in identifying what’s working and pursuing it with full force. Many startups fail because they spread themselves too thin or hesitate to chase their most promising ideas. Instead, Altman advocates for doubling down when you see strong signals of success.
Why Hesitation Happens
Hesitation often stems from fear: fear of over-committing, fear of failure, or fear of placing all bets on one card. In Thiel’s case, even someone with his foresight second-guessed an opportunity that seemed obvious in hindsight. This underscores how even seasoned professionals can struggle to see the full potential of an idea in its early stages.
A Real-Life Application: Airbnb’s “Crazy” Potential
A great example of this principle is Airbnb. Early investors were skeptical about the idea of people renting out rooms in their homes. Those who hesitated missed out on a company now valued at over $100 billion. The investors who recognized its potential and leaned in aggressively reaped massive rewards.
The Mindset Shift: Boldness in Action
Altman’s takeaway is simple but profound: train yourself to recognize momentum and act decisively. This doesn’t mean taking reckless risks but rather being brave enough to back your instincts when evidence supports them.
Peter Thiel’s admission isn’t just a lesson in investing; it’s a call to embrace bold decision-making in all aspects of life and business. When you see something working—whether it’s a product, a market trend, or a startup—don’t just watch it grow. Be part of its story.
