The market is brutally efficient at correcting overconfidence, but almost infinitely patient in tolerating underperformance disguised as prudence. The real risk most institutions face is not that they will lose money, but that they will fail to make it — and never be called to account for that failure.
A good idea is not enough. The question is always: compared to what? Every investment, every business decision, every allocation of time is a choice among alternatives. The failure to think in terms of opportunity cost is the single most common and costly mistake I see intelligent people make.
The difficulty in life is the choice. And it is a difficulty because, in making a choice, we must leave behind the unselected remainder — which haunts us, sometimes, as the ghost of what we might have been.
The big difference between successful people and unsuccessful people is that successful people say no to almost everything.
Every major technological boom has produced the same figure, the person who gives everything to the wave. During the industrial revolution, it was the factory worker. During the Gold Rush, it was the men who left their families and headed west. During the dotcom boom, it was the founders sleeping under their desks in SoMa. Now, it is the person who is building, building, always building — vibe coding at midnight, constantly upgrading their models—convinced that stopping for five minutes means missing everything.
We were in a really great place as a business. But the cost of spending time on things that aren't important, or that you believe don't have a future, is immense.
I realized I could either continue to drain myself for a small expense, or let it go and focus on the projects in front of me. I had, unknowingly, engaged in maladaptive frugality.
The best business decision is often the one you don't make. Most of life's errors come from doing too much, not too little. Your job is to say no to a thousand good ideas so you can say yes to the one that matters.
The goal of a business is to make money. The goal of a life is to avoid regret. These are often in conflict, and the resolution of that conflict is what separates a life well-lived from a merely profitable one.
The best time to repair the roof is when the sun is shining. Once it starts raining, it's too late. Most people wait until there's a crisis, but the best businesses invest in capabilities and relationships before they desperately need them.
The best business decision is often the one you don't make. Most of life's errors come from doing things, not from leaving them undone.
The difficulty in life is the choice. When you are young, there seems to be so much time and so many choices, none of which seems to matter very much because it seems that later on you can always choose again. But then, suddenly, you are old.
The best business decision is often the one you don't make. Most of life's errors come from doing the wrong thing, not from doing nothing.
It's opportunity costs, not marginal costs, that are the challenge facing hyperscalers. How much compute should go to customers, and which ones? How much should be reserved for internal workloads?
The best business decision is often the one you don't make. Inaction has a cost that most entrepreneurs systematically underestimate because they can't see the counterfactual.
The best investment you can make is in yourself. But most people won't because it's not tangible—you can't point to it on a balance sheet. Yet it compounds faster than any stock.
The difference between successful people and really successful people is that really successful people say no to almost everything.
The best investment you can make is in yourself. But most people won't because it's not a leveraged bet, and you can't borrow money to do it.
