Afterword: You Can’t Read People

One more thing before you go. Something I learned after everything in this book, not during it.

You will be wrong about people.

I don’t mean sometimes. I mean regularly. Consistently. In ways that will embarrass you if you’re paying attention.

Everyone is wearing a mask. Not because they’re fake — because they’re scared. The loudmouth at the bar who seems like an ass? He’s covering for something. The quiet woman who never talks to anyone? She might be the most generous person in the room once someone earns her trust. The guy who rubbed you wrong on the first three meetings might become the person who drives two hours to help you when nobody else picks up the phone.

I’ve seen it happen. I’ve been wrong so many times about who would show up and who wouldn’t that I stopped pretending I could predict it.

This book talks a lot about reading returns, spotting cooperators, identifying defectors. And that’s real — patterns matter, data matters, paying attention matters. But here’s what I need you to hold alongside all of that:

You are not as good at reading people as you think you are. Nobody is.

The most disagreeable people sometimes turn out to be the most caring. They just don’t perform it. They don’t smile on cue. They don’t say the right things at the right times. They show their care through action, buried under layers of rough edges and bad first impressions. And if you wrote them off because they didn’t fit your idea of what a cooperator looks like, you missed something real.

Meanwhile, some of the warmest, most charming people you’ll ever meet will let you down when it counts. They’ll say all the right things and do none of them. The performance is flawless. The follow-through is empty.

Charisma is not character. I said that earlier in this book. But the reverse is just as important: lack of charisma is not lack of character.

Some of my best investments — the ones that returned the most, the ones that built the deepest trust — were in the weirdest places. People I almost didn’t talk to. People who didn’t seem like “my kind of person.” People who the rest of the room had already written off.

That’s the thing about social capital. It doesn’t follow your predictions. It doesn’t care about your first impressions. It rewards patience, curiosity, and the humility to admit that you don’t know who someone is after one conversation, or five, or ten.

So read the returns, yes. Pay attention, yes. But hold it all loosely. Stay open to being surprised. Stay open to the person who doesn’t fit the pattern, who doesn’t match the profile, who makes you uncomfortable in a way you can’t quite name.

Sometimes the biggest return comes from the place you least expected it. And sometimes the person who looked like a sure thing turns out to be made of smoke.

You can’t read people. Not fully. Not ever. And especially not on the first meeting. First impressions will fool even the most seasoned readers — they always have, they always will. The true skill was never in reading the room on night one. It’s in reading the responses over time. The pattern across months. The trend across years. That’s where the real data lives. Everything before that is just noise dressed up as intuition.

The best you can do is show up, be generous, pay attention, and leave room for the possibility that you’re wrong about almost everyone.

That’s not a flaw in the strategy. That’s the whole point of staying in the game long enough to find out.

I need to tell you about Jake Jimmerson.

Jake was my roommate for one semester in school. One semester. And in that time he taught me more about myself than any friend I’ve ever had.

I hated him at first. For a solid month, I couldn’t stand him. He rubbed me wrong in every way a person can rub you wrong. If I’d been following my own advice from Chapter 9 — reading the early returns — I might have pruned him after week two. And I would have made the worst mistake of my life.

Because over time, Jake broke open. Not all at once — slowly, in pieces, the way real people do when they decide to trust you. And what was underneath all those rough edges was the most wonderful person I have ever known.

He didn’t just have my back in the obvious situations. He had my back in the weird ones. The odd thoughts, the strange rabbit holes, the parts of me that most people would have smiled politely at and changed the subject. Jake didn’t change the subject. He jumped in. He pushed me further down my own rabbit holes — but in a playful way, a way that made me learn, a way that made me feel like the weird parts of me were the best parts.

And most importantly, he shared everything with me. The things most people will never share. The real stuff. The stuff behind the mask. He gave me access to who he actually was, not who he performed being, and that kind of trust changed something in me permanently.

We only had one semester. Then school ended, and we went our separate ways. Two years went by. I always meant to go see him. I always thought there would be time.

Then Jake passed away. And I never got to see him again.

I wish I had gone. Even one more time. Even for an hour. I wish I had treated that relationship with the urgency it deserved instead of assuming it would always be there.

This book is dedicated to Jake Jimmerson.

Because he was the living proof of everything in these pages — that the most disagreeable first impression can hide the most extraordinary person. That one semester can matter more than a decade. That the people who change your life don’t always look like what you expected.

And because he taught me, without ever trying to, that the only thing worse than investing in the wrong person is failing to invest in the right one while you still can.

Show up. Remember names. Follow through.

And don’t wait. Don’t ever wait.

For Jake.
