I want to tell you about two people.
The first one sits at a blackjack table. He’s been playing for three hours. He’s down €400. Every rational signal in his brain is telling him to stop — but he doesn’t. He increases his bet instead. He needs to win back what he lost. He can feel it coming. One more hand.
The second one checks his investment portfolio on a Tuesday morning in March 2020. The market has dropped 30% in three weeks. Everything he’s read tells him this is temporary. Everything he knows about long term investing tells him to stay calm. But he can’t. He sells everything. He’ll buy back in when things stabilize. He just needs to stop the bleeding.
I’ve watched the first person thousands of times from behind a surveillance camera.
I was almost the second person.
And here’s what twelve years in casino surveillance taught me that most financial advisors won’t tell you — these two people are making the exact same mistake, driven by the exact same psychological mechanism, in two completely different settings.
The Brain Doesn’t Know the Difference
Daniel Kahneman spent his career proving something that feels uncomfortable to accept: we are not the rational decision makers we believe ourselves to be.
In Thinking Fast and Slow he describes two systems that govern our thinking. System 1 is fast, emotional, and automatic. System 2 is slow, deliberate, and rational. The problem is that when money is involved — especially when we’re losing it — System 1 takes over completely before System 2 even has a chance to respond.
The casino player who increases his bet after a loss isn’t stupid. He’s human. His brain has detected a threat — the loss — and responded with an instinctive drive to neutralize it immediately. The fact that increasing the bet is statistically irrational is completely irrelevant to System 1. System 1 doesn’t do statistics. It does survival.
The investor who sells everything during a market correction is doing exactly the same thing. The market dropping 30% feels like an emergency. System 1 screams “get out.” The fact that historically markets always recover, that selling locks in the loss permanently, that the rational move is to stay or even buy more — none of that reaches System 1 in time.
Same brain. Same mechanism. Different table.
Loss Aversion — The Most Expensive Human Trait
Kahneman also identified something called loss aversion — the fact that losing €100 feels roughly twice as painful as gaining €100 feels good. We are not wired symmetrically around money. Losses hit harder. Always.
This is why the casino player can’t walk away. The pain of the loss already suffered is more powerful than the rational calculation of future losses. He’s not chasing a win. He’s trying to escape the pain of what he’s already lost.
And this is why — even after freeing up significant money every month after paying off our mortgage in 2023 — I still spent two years knowing everything I needed to know about investing and not investing a single euro of my savings.
Let me give you the full picture because the timeline matters.
For the first three years after our financial wake up moment in 2020, my wife and I directed every available euro toward paying off our mortgage early. We had 23 years left. We paid it off in three. During those three years we couldn’t invest — and we didn’t need to. We had a clear mission and we executed it completely.
Then the mortgage was gone.
Suddenly we had significant monthly cash flow that had been going to the bank for years. We had the money. We had the knowledge — I had read every major investing book, watched countless podcasts, understood ETFs, dollar cost averaging, long term market behavior, and the mathematics of compound interest. I understood everything.
And I still waited two years before investing a single euro.
I told myself I needed more information.
I didn’t need more information. I had more than enough. What I needed was to make peace with the possibility of loss — and my brain, wired exactly like every other human brain, was fighting that peace with everything it had.
Two years. The mortgage was paid. The money was available. The knowledge was complete. And loss aversion — disguised as due diligence — kept me exactly where I was.
The Day Everything Changed
My first investment was small. Deliberately, almost embarrassingly small. Not because I couldn’t invest more — but because small felt survivable. If I lost it, I could absorb it. System 1 could tolerate it.
And something strange happened the moment I pressed the button.
Everything normalized.
Not because the market suddenly became less volatile. Not because I had finally found the piece of information I’d been missing for two years. But because the action itself broke the paralysis. I had skin in the game — to use Nassim Taleb’s phrase — and the world hadn’t ended.
From that moment the journey accelerated. I understood dollar cost averaging not just intellectually but emotionally — investing a fixed amount every month regardless of market conditions, buying more units when prices are low and fewer when prices are high, removing the impossible burden of trying to time the market perfectly.
I understood that market corrections are not catastrophes — they are the price of admission for long term returns. When the market drops I buy more units with the same monthly amount. When the market rises my existing portfolio grows. On a long enough timeline — and we’re talking at least ten years — the market has historically always recovered and grown. The only people who truly lose are the ones who panic and sell at the bottom.
My wife opened her own investment account shortly after — building her own portfolio on XTB according to her own risk profile, her own comfort with volatility, her own timeline. Two people in the same household, completely aligned on the destination, taking their own roads to get there.
Five years from first contact with investing information to actually investing. Three of those years intentionally redirected toward eliminating debt. Two of those years lost to loss aversion disguised as research.
I’m telling you this not to impress you — but because if you are currently sitting on money you know you should be investing, reading one more book, watching one more podcast, waiting for one more signal that it’s safe — I want you to recognize yourself in this story.
The Fun Player Knows Something the Retail Investor Doesn’t
In every casino there are players who consistently have a good time. They’re rarely the high rollers. They’re usually quiet, ordinary people who arrived with a fixed budget they’d already mentally spent — entertainment money, like a concert ticket. They don’t chase losses. They don’t increase bets when they’re down. When their budget runs out, they leave. No drama.
They’ve accepted the possible loss before they started. That acceptance is what sets them free to enjoy the experience without being destroyed by the outcome.
The most successful long term investors operate the same way. Morgan Housel in The Psychology of Money describes it perfectly — the goal isn’t to maximize returns. It’s to find a strategy you can actually stick to through volatility, through corrections, through the moments when every instinct screams at you to get out.
Accepting that your portfolio will drop sometimes — before it happens, not during — is the investing equivalent of the fun player’s fixed budget. It doesn’t prevent the loss. It prevents the loss from making your decisions for you.
What The Surveillance Camera Sees
From behind a surveillance camera you develop a particular skill — you learn to distinguish between people who are in control of their decisions and people whose decisions are being made for them by their emotional state.
The tell is almost always the same. Controlled players are consistent — their behavior doesn’t change dramatically based on recent outcomes. Emotional players escalate — their bets get bigger after losses, their decisions get faster, their reasoning gets louder and more elaborate.
The same tell exists in investing. The controlled investor has a plan and follows it regardless of what the market did last week. The emotional investor is always reacting — buying after things have already gone up, selling after things have already gone down, always one step behind the market, always on the wrong side of their own emotions.
You don’t need a surveillance camera to spot this pattern.
You just need to watch your own behavior the next time the market drops.
The Simple Truth
Casinos and stock markets are very different places. But the human being sitting at the table and the human being watching their portfolio on a phone screen are running the same operating system.
Loss aversion. Recency bias. The desperate need to feel in control. The inability to sit with uncertainty. The search for one more piece of information before finally acting.
Understanding this doesn’t make you immune to it. I spent two years understanding it perfectly and it still paralyzed me.
But it gives you something valuable — the ability to recognize what’s happening when it’s happening. To notice when System 1 has taken the wheel. To pause long enough for System 2 to ask: is this a rational decision, or is this fear?
That pause is worth more than any stock tip.
I’ll be watching.
