Most people think of risk as the probability of losing money. But the real risk is that you'll be forced to sell at the wrong time — that circumstances, not judgment, will determine your outcome. Volatility is only dangerous if it can compel you to act.

The best investment you can make is in businesses you understand, and the second-best is in your own ability to understand more businesses. Most investors do neither — they buy what's rising and call it research.

Most people overestimate what they can do in one year and underestimate what they can do in ten years. But the subtler error is assuming the next ten years will look like the last ten — the truly dangerous assumption for any investor or builder.

Leverage is the difference between outcomes in a world that looks similar on the surface. Two investors can have the same insight, the same conviction, and the same patience — but the one who sized correctly will retire while the other merely survives. Position sizing is not a detail; it is the strategy.

The chains of habit are too light to be felt until they are too heavy to be broken. A young person who consistently saves a small amount will find, decades later, that the habit has built a fortress; a young person who defers saving will find the habit of spending has built a prison.

The biggest mistake investors make is to believe that what happened in the recent past is likely to persist. They assume that something that was a good investment in the recent past is still a good investment. Typically, high past returns simply imply that an asset has become more expensive and is a less compelling investment.

The trick is to keep learning. If you stop learning, other people will pass you by. Temperament alone won't do it — you have to keep learning, because the world keeps changing, and you have to keep up with it and even get ahead of it.

The best business returns are usually achieved by companies that are doing something quite similar today to what they were doing five or ten years ago. That is no accident.

Most people overestimate what they can do in one year and underestimate what they can do in ten years. But the deeper error is that they plan in one-year chunks at all — the unit of compounding is decades, not quarters.

The difference between a good business and a bad business is that good businesses throw up one easy decision after another. The bad businesses throw up painful decisions time after time.

The biggest mistake investors make is to believe that what happened in the recent past is likely to persist. They assume that something that was a good investment in the recent past is still a good investment. Typically, high past returns simply imply that an asset has become more expensive and is a poorer, not better, investment.

The ability to sit quietly and patiently while everyone else is acting is not a passive virtue — it is the hardest-won competitive advantage in investing. Most of the damage investors do to themselves comes from the compulsion to do something when the right action is nothing.

The lesson of history is that there have always been more buyers of stability than sellers of it. When uncertainty rises, the price of certainty rises with it — and those willing to sell certainty at that moment earn returns that compound for decades.

The biggest moat a business can have is not technology, not patents, not brand — it's the accumulated trust of customers who would feel genuine loss if you disappeared. Trust is the only asset that appreciates purely through use and deteriorates purely through neglect.

Most people think of risk as the probability of losing money. But the real risk is behaving in a way today that prevents you from being in the game tomorrow. Permanent impairment of capital is far less common than permanent impairment of judgment under pressure.

The greatest competitive advantage in business is a long time horizon. Almost all of the gains in any market come from people willing to wait longer than everyone else is willing to wait, and almost nobody is structurally set up to do that.

The market is a device for transferring money from the impatient to the patient. But what most people miss is that patience isn't passive — it requires the active courage to hold while everything around you screams sell.

Most people overestimate what they can do in one year and underestimate what they can do in ten years. The long-term compounder who does nothing dramatic usually beats the person executing a brilliant short-term strategy.

The best investment is in the business that compounds the fastest while requiring the least capital. Most people think about return on capital. They should think about return on capital per unit of risk taken.

The difference between a good business and a great business is that a good business earns a fair return on capital employed, but a great business earns exceptional returns on capital while reinvesting at those same exceptional rates.

The big money is not in the buying and selling, but in the waiting. Patience is the virtue that is most rewarded in investing.

The best thing you can do is compound money at high rates of return for a long time. That's the game. Most people don't understand that the biggest returns come from sitting, not trading.

The best investment is in the business that compounds the fastest while requiring the least capital to do so. Most people focus on the numerator and ignore the denominator.

The best way to get smart is to try to be a little smarter than you were the day before. But the way to get rich is to try to be a little richer than you were the day before.

The difference between a great business and a mediocre one is often that the great business keeps compounding capital at high rates of return for decades, while the mediocre business cannot. Most people underestimate how powerful this difference becomes over time.

The best investment is in the business that compounds the fastest while requiring the least reinvestment. Most people focus on the first part and ignore the second, which is why they end up with businesses that eat cash.

The big money is not in the buying and selling, but in the waiting. You have to be willing to let your profits run and cut your losses short.

The best thing a company can do is compound capital efficiently over a long period of time. Everything else is details.

The big money is not in the buying and selling, but in the waiting. You have to be willing to hold. Most people aren't.

The difference between investment success and mediocrity is often not intelligence—it's the ability to do nothing when nothing should be done. Most investors feel compelled to act, when the great fortunes are made by inaction.

The big money is not in the buying and selling, but in the waiting. You have to sit on your ass and do nothing.

The best thing a company can do is compound capital efficiently over a long period of time. That's what creates shareholder value. Most companies don't do it because they're distracted by quarterly earnings, acquisitions that destroy value, or just bad capital allocation decisions.

The best thing a company can do is compound capital efficiently over decades. Everything else is noise.

The difference between a business that compounds and one that doesn't is often not the talent of the founder, but the defensibility of the moat—and most founders underestimate how much time it takes to build one.

The difference between a business that compounds and one that doesn't is often not the brilliance of the idea, but the willingness to accept small returns for decades while reinvesting everything. Most people can't do this psychologically.

The best thing a company can do is compound capital efficiently over decades. But the second-best thing is to be so boring that people forget to worry about you.

The best investment is in yourself. But the second-best investment is often in things that are so obvious and so important that nobody is paying attention to them because everyone assumes someone else is handling it.
