There are two ways to lose money in the stock market. The first is to be wrong. The second is to be right but not long enough.

I’ve done both. The second one hurts more.

I had done the work. Weeks of it. Financial statements, competitive analysis, management track record. The thesis was sound. I bought with conviction, the kind of conviction you feel in your chest.

Then the stock dropped. Not a crash. Just a slow bleed. Down 8%. Then 12%. I refreshed my portfolio in the morning. I refreshed it at lunch. I refreshed it before bed. Each time, a small knot tightened in my stomach.

The drop wasn’t the problem, stocks drop. The problem was what the drop did to my perception of time. Suddenly I wasn’t thinking in years. I wasn’t thinking about the business at all. I was thinking in days, watching the number, waiting for it to climb back to where I started.

Three weeks later, it did. A small gain. I sold.

The relief was immediate. Physical. Like setting down something heavy.

Within a year, the stock had tripled. My analysis was right. The business did exactly what I expected. The only thing that failed was my ability to stay in the game long enough for my conviction to pay off.

This is the trap Luca Dellanna dissects in Winning Long-Term Games: the way to win long-term games is to stop playing them as a succession of separate short-term games. Most of us know this intellectually. Few of us do it. The moment pressure arrives; a loss, a setback, a competitor pulling ahead, our time horizon contracts, and we start optimizing for the wrong game.

What Did I Get Out of It

Play Short-Term Games to Win the Long-Term One

The core insight of the book is not that you should avoid short-term games. It’s that you should play them differently.

Winning long-term games isn’t about going slow or avoiding short-term games. It’s about playing short-term games as parts of long-term ones, not to win the former but to win the latter.

Most of us treat each interaction, each project, each decision as its own game with its own score. We optimize for the immediate outcome. Did I win this negotiation? Did I get the most out of this deal? Did I hit this quarter’s target?

Dellanna argues this is backwards:

Interact with people not to get the most out of each interaction, but to improve the next one.

When you negotiate a deal, the goal isn’t maximum extraction, it’s a fair outcome that makes your counterpart want to deal with you again. When you delegate a task, the goal isn’t just completion, it’s building your delegee’s skills so future delegation becomes easier. When you give feedback, the goal isn’t just correction, it’s leaving the recipient more capable and more willing to hear feedback next time.

When performing a task, focus not only on getting it done this time, but also on learning how to get it done better or faster the next time.

When delegating a task, do it not just to get something done, but also in such a way that your delegee’s skills and engagement increase.

When giving negative feedback, do it in such a way that not only does the recipient correct their mistake but also feels empowered.

Each short-term game is a setup for the next one.

Do not (just) take action for its direct outcome, but rather to make your future actions easier or more effective.

Reproducible Strategies Over Fast Results

We are obsessed with speed. Fastest growth. Quickest path to success. First to market. But Dellanna makes a distinction that changed how I evaluate both my own strategies and those I observe in others:

Short-term players care only about their rate of growth. Long-term players also care about their growth rate, obviously, but only the portion that is achieved on solid foundations and is likely to continue in the future. Long-term players do not care about unsustainable success.

The question isn’t “how fast did they grow?” The question is “could I replicate that growth if I copied their strategy?”

Of all the successful people, only a few succeeded with reproducible strategies. Instead, most succeeded with non-reproducible strategies: strategies that, if you imitated them, your chance of success would be low. You shouldn’t imitate those.

This is where most of us go wrong. We see someone succeed and assume their strategy caused their success. But success is a poor filter. Many people succeed despite their strategy, not because of it. Luck, timing, and circumstances invisible to us played a larger role than the tactics we can observe.

Stop using short-term growth rates to estimate the quality of a strategy. While good strategies, on average, grow faster than bad ones, it’s also true that rapid growth can be due to unsustainable factors such as luck, excessive risk-taking, or behaviors with short-term benefits and long-term costs.

The key metric isn’t speed. It’s probability.

Because we only have one life, a strategy’s probability of success is its most important attribute, and speed and efficiency should be secondary to it.

This doesn’t mean avoiding risk. It means understanding which risks are acceptable:

Good strategies aim for certainty of success, but that doesn’t mean they avoid gambles that might not work.

Long-term strategies can contain risky projects, but those projects should only be risky in the sense that they might not work, and never in the sense that their failure might endanger the strategy.

The distinction is crucial. You can bet on projects that might fail. You cannot bet on strategies that might fail. The former is entrepreneurship. The latter is gambling with your future.

The Comparison Trap

There will always be someone ahead of you. Someone who got promoted faster. Someone whose company grew quicker. Someone whose portfolio outperformed yours.

The temptation is to study what they did and copy it. This is often a mistake.

There will always be someone who achieves success faster than you. That doesn’t necessarily mean that they have a better strategy than yours. Maybe they do, but probably they don’t. What matters is not the outcome that their strategy produced for them but the distribution of outcomes that their strategy is likely to yield.

Dellanna introduces a concept he calls “hindsight gerrymandering”, using hindsight to draw boundaries around successful outcomes and call it a strategy:

Survivorship bias is particularly treacherous because of a phenomenon I call hindsight gerrymandering.

Using hindsight to draw a non-existent boundary between a good and a bad strategy is the most common reason that otherwise very smart investors temporarily forget survivorship bias and get lured into adopting money-losing strategies.

The advice is direct:

Never compare yourself to someone with a shorter time horizon. Doing so will mislead you into making suboptimal choices.

Never envy someone with a strategy that produces a worse distribution of outcomes than yours, even if, for them, it did produce a better outcome.

Someone else’s success doesn’t validate their strategy. Their strategy might have had a 10% chance of working and they got lucky. Yours might have a 90% chance and simply hasn’t paid off yet. Copying them would be moving from a good bet to a bad one.

Never judge a strategy based on what happens if it works, but judge it based on what happens if it doesn’t.

The feeling of falling behind is powerful. Dellanna acknowledges this:

Short-term success is more likely due to luck or short-term optimization than competence. Yet, the feeling of falling behind is strong. And it is precisely this feeling of falling behind that makes many of us switch from good long-term strategies to poor short-term ones.

Resist it.

Build Long-Term Assets

Here’s an uncomfortable truth:

Building long-term assets (such as skills, habits, relationships, etc.) never makes sense in the short term (there is always a faster way to meet short-term objectives), yet it is necessary for long-term success.

Building long-term assets never makes sense in the short term. There’s always something more urgent, something with a faster payoff, something that looks more productive right now.

This is precisely why most people don’t do it. And precisely why it’s valuable.

Your long-term success is limited to what your long-term assets allow. Increase your long-term assets, and you automatically increase your long-term potential.

The practical advice:

Dedicate at least a couple of hours a week to doing things that may not make sense in the short term but are essential for the long term.

What does this look like? Learning a skill you won’t use for years. Maintaining relationships with no immediate benefit. Building habits whose payoff is invisible today. Writing, reading, thinking; activities that don’t show up on this quarter’s scorecard.

The alternative is fragility:

If you aim to achieve your financial objectives solely through the accumulation of money and without also accumulating know-how and relationships, your financial capital will be extremely fragile.

Money without skills can be lost. Success without relationships can’t be sustained. Achievements without underlying capability will eventually be exposed.

Start doing what doesn’t make sense now but is necessary for the long term. Your Future Self will thank you.

Risks Accumulate

A 5% annual chance of failure seems small. Over 20 years, it’s a 64% chance of failure.

This is the math that most people ignore:

Time horizons matter, and risks accumulate. If you want to succeed in the long term, you cannot afford to use tactics that carry a risk of ruin, however small.

Dellanna points out that risk management looks wasteful in the short term, because in the short term, it is:

Thinking about how you might fail is superfluous in the short term in the sense that, in the short term, risks are unlikely to materialize, and thus, any risk management activity appears to be a waste of time. However, it is not superfluous over the long term, over which even unlikely risks have a significant chance of materializing.

The key distinction is between risks that set you back and risks that take you out:

Take risks, but never risks that might damage your long-term assets (capital, trust, health, etc.).

You can afford bets that don’t work. You cannot afford bets that, if they don’t work, end the game entirely.

This reframes risk management not as caution but as enablement:

Just like brakes are not for driving slowly but for enabling driving fast, risk management is not a burden but an enabler of fast growth.

Learn From Failure Before It Happens

Most of us learn from failure the hard way. We make the mistake, suffer the consequences, and then adjust. Dellanna argues this is backwards:

Learning from your failures after they happen is painful. It’s better to learn from your failures before they happen. This is possible with the use of premortems and fishbone diagrams.

The question to ask isn’t “what should I do to succeed?” It’s the opposite:

“What might cause me to fail, and what can I do about it?”

This sounds simple. It isn’t. We don’t like thinking about failure. We especially don’t like thinking about the failures that feel personal; the ones tied to our weaknesses, our blind spots, our uncomfortable truths.

Our path toward success is paved with lessons we do not want to learn, and the way forward consists of asking ourselves what unpleasant lessons we have been avoiding.

Dellanna pushes further. Don’t just identify the failure, identify what leads to it:

Instead of avoiding the mistake, avoid the conditions that lead to that mistake. For example, if “doing drugs” is a common reason for failure, don’t ask yourself whether you might do drugs. Ask yourself what could lead you to do drugs and prevent that.

Base rates matter here. If something commonly kills others in your position, it’s probably a threat to you too:

Do not underestimate base rates. If a risk frequently causes failure for others, it is very likely to be a major risk for you as well, even if you feel immune to it.

We all feel immune. We all think we’re different. Usually we’re not.

The goal isn’t a strategy that might work. The goal is higher:

You shouldn’t be satisfied with a strategy that might work. You want to adapt your strategy so that your success is inevitable.

Inevitable is a strong word. But the mindset shift matters. Instead of hoping your strategy works, engineer it so that failure becomes difficult.

If you successfully think about all the ways in which you might fail, as well as how others with similar objectives have failed, you will bulletproof your strategy and dramatically increase your chance of success.

Avoid Races to the Bottom

Some games aren’t worth winning. Dellanna calls these “races to the bottom”:

A race to the bottom is a race where the winner is the person who’s willing to take more risks and/or make more sacrifices.

These races are seductive. They look like competition. They feel like ambition. But they’re traps. The winner is whoever is willing to destroy the most; their health, their relationships, their integrity, to get ahead.

It focuses on a single area of your life and neglects the rest. It might bring you a pyrrhic victory, in which you achieve your objective, but it might still not matter because you have compromised another important area of your life.

The alternative isn’t to stop competing. It’s to compete in a different category:

Instead of aiming to be the most successful, aim to be the most successful among those who play long-term games and are not willing to take excessive risks or make excessive sacrifices.

This reframe is liberating. You’re not competing against everyone. You’re competing against those who share your constraints, who also refuse to burn their health, betray their values, or neglect their families.

Never compare yourself with someone who has different priorities or is optimizing for different objectives or for a shorter time horizon.

And here’s the surprising part:

The bar isn’t that high if you look at the aggregate instead of individual attributes.

Most people optimize for one thing at the expense of everything else. If you can be good; not great, just good, across multiple dimensions, you’re ahead of almost everyone.

The path toward excellence and a great life involves going broad and narrow.

Narrow excellence requires broad excellence to yield good outcomes.

The person who builds wealth but destroys their health hasn’t won. The person who succeeds at work but fails at home hasn’t won. Winning long-term games means winning across the board, or at least not losing catastrophically in areas that matter.

Who Is This For

Dellanna’s book is short. You can read it in an afternoon. But the ideas are dense, and they compound the longer you sit with them.

This is a book for anyone who has felt the pull of short-term optimization, the urge to take the quick win, copy the fast grower, or abandon a sound strategy because the results aren’t coming fast enough. It’s for anyone who has made decisions they later regretted because, in the moment, their time horizon collapsed.

It’s particularly useful for anyone whose success depends on compounding (that is just about everyone), where early mistakes echo for years and where the difference between a good strategy and a bad one often isn’t visible until it’s too late to switch.

The core message is simple enough to fit on an index card: play short-term games to win long-term ones, not the other way around. But simple isn’t the same as easy. The pressure to optimize for now, to close the gap, to keep up, to show progress, never goes away.

What this offers is a framework for resisting that pressure. Not by ignoring short-term results, but by evaluating them correctly. Not by avoiding risk, but by distinguishing between risks that might not work and risks that might end the game. Not by going slow, but by going in a direction you can sustain.

I think back to the stocks I sold too early. The thesis was right. The businesses performed. The only thing that failed was my time horizon. Reading Dellanna, I understand better why that happened, and what I need to do differently next time.

The goal isn’t to never feel the pull of short-term thinking. The goal is to recognize it when it happens and refuse to let it dictate your decisions.

That’s how you win long-term games.
