Success is a weird drug. One minute you’re grinding in relative obscurity, and the next, everyone is laughing at your jokes and telling you you’re a genius. It feels good. It feels amazing, actually. But there is a reason your parents or that one crusty old mentor always told you, "don't let it go to your head." They weren't just trying to rain on your parade or keep you humble for the sake of manners. They were giving you a survival strategy.
When we talk about someone "getting a big head," we usually mean they’ve become arrogant. But from a psychological perspective, it's way more dangerous than just being a jerk at dinner parties. It’s about a total loss of perspective. You start believing your own press releases. You start thinking the rules don’t apply to you. And that is exactly when the floor drops out.
I’ve seen it happen to startup founders who raise a Series A and suddenly think they’re Steve Jobs, only to burn through their cash on ergonomic espresso bars. I’ve seen it with writers who get one viral hit and then stop editing their work because they think every word they touch turns to gold. It’s a trap.
The Science of Success and the Ego Trap
There is this thing called the Hubris Syndrome. It’s not an official clinical diagnosis in the DSM-5, but researchers like Lord David Owen and Jonathan Davidson have spent years studying it in political leaders and CEOs. They found that power actually changes the way the brain functions. Specifically, it can diminish the capacity for empathy and realistic risk assessment. Basically, success makes you kind of "brain damaged" in the areas that help you stay grounded.
When you start to feel invincible, your brain stops looking for red flags. You stop listening to feedback. Why would you listen to a "hater" when you’re clearly winning, right? This is the core of why people say don't let it go to your head. It’s a warning against the cognitive decline that comes with winning.
Take a look at the "Sophomore Slump" in music or sports. A rookie has a breakout year because they are hungry, they practice ten hours a day, and they listen to their coaches. Then they get the big contract. They get the cover of the magazine. They start believing they are "naturally" gifted rather than "practiced." They stop doing the boring stuff that made them successful in the first place.
Why We Fall for Our Own Hype
Honestly, it’s just easier to believe we are special.

If I tell you that your success was 50% hard work and 50% sheer, dumb luck (like being in the right room at the right time), you’ll probably get defensive. We want to own our wins entirely. Psychologists call this the Self-Serving Bias. We attribute our successes to our internal character and our failures to external "bad luck."
- Winning a game? "I’m a tactical genius."
- Losing a game? "The sun was in my eyes and the ref was biased."
This bias is the fuel for a "big head." If you don't actively fight it, you’ll eventually lose the ability to see reality clearly. You’ll make bad investments. You’ll alienate your best employees. You’ll ruin your relationships because you think you’re too important to do the dishes or listen to your partner’s day.
The Dangers of the "Yes-Man" Echo Chamber
One of the quickest ways to let it go to your head is to surround yourself with people who need something from you. When you’re at the top, people stop telling you "no." They stop telling you your ideas are half-baked.
Look at some of the biggest corporate collapses in history. Whether it’s the spectacular fall of Enron or the more recent chaotic swings in the tech world, there is usually a leader at the center who stopped hearing the word "no" years ago. They built a culture where dissenting voices were seen as "not being team players." That’s the ego speaking. It’s a protective shell that eventually becomes a coffin.
Practical Ways to Keep Your Feet on the Ground
So, how do you actually do it? How do you celebrate a win without becoming a caricature of yourself?
It’s about intentional friction. You have to build systems into your life that remind you that you’re just some person.

1. Keep "Pre-Success" Friends Close
The people who knew you when you were broke or struggling are your greatest asset. They don't care about your new title. They remember the time you accidentally locked yourself out of your apartment in your underwear. They provide the "social leveling" you need to stay sane. If you find yourself only hanging out with people who are "at your level," you’re in trouble.
2. Practice Deliberate Self-Criticism
Every time you have a major win, force yourself to write down three things that went wrong or three ways you got lucky. It sounds pessimistic, but it’s actually grounding. It forces your brain to stay in "analysis mode" instead of "celebration mode."
3. The "Janitor" Test
How do you treat people who can do absolutely nothing for you? If you’re being extra charming to the VP but you’re short with the barista, it’s already gone to your head. Period. Your character isn’t defined by how you treat your peers; it’s defined by how you treat people you perceive as "below" you in some hierarchy.
The Nuance: Confidence vs. Arrogance
Let’s be real: you do need some level of ego to do anything big. To start a business, to get on stage, or to lead a team, you have to believe you’re capable. If you have zero ego, you’ll never take a risk.
The trick is keeping the ego in the "engine room" rather than the "captain’s chair."
Confidence is: "I have the skills to solve this problem if I work hard."
Arrogance is: "This problem isn't even a challenge for someone like me."

One is fueled by competence; the other is fueled by a delusion of superiority. When people tell you don't let it go to your head, they aren't telling you to be insecure. They are telling you to keep your confidence rooted in reality and effort, not in your status or your bank account.
Why Humility Is a Competitive Advantage
In the 2026 job market, "soft skills" are becoming the only thing AI can't easily replicate. Humility is a massive part of that. A leader who can admit they were wrong is a leader people actually want to follow. A creator who can take harsh feedback and use it to get better is the one who stays relevant for twenty years instead of two.
Arrogance is brittle. It breaks when it hits a real obstacle. Humility is flexible. It allows you to pivot, to learn, and to grow.
Actionable Steps for Staying Grounded
If you feel like you’re starting to believe your own hype, here is a quick "ego audit" you can do this week.
- Ask for a "Roast": Find a trusted colleague or friend and ask them to tell you one thing you’ve been doing lately that’s annoying or ineffective. And here is the hard part: you aren't allowed to defend yourself. Just say "thank you" and think about it.
- Do something you’re bad at: Start a new hobby where you are a total beginner. Being a "loser" at pottery or Brazilian Jiu-Jitsu is incredibly good for the soul. It reminds you what it feels like to struggle and learn.
- Audit your "I" count: Look at your last few emails or social media posts. How many times did you use "I" or "me" versus "we" or "the team"? It’s a small thing, but it reflects your internal focus.
- Practice Gratitude (The Non-Cringey Way): Don't just do a "gratitude journal." Actually reach out to someone who helped you get where you are and tell them specifically what they did. Acknowledging that you didn't get here alone is the ultimate antidote to a big head.
Stay Hungry, Stay Small
The world loves to build people up just to watch them fall. It’s a classic narrative arc. The best way to avoid the fall is to never climb onto the pedestal in the first place.
Enjoy your success. Buy the nice shoes. Take the vacation. But at the end of the day, remember that you’re still just a human being trying to figure it out, just like everyone else.
Keep your head the same size it was when you started. It’ll make the journey a whole lot easier, and you’ll find that people actually want to stay on the ride with you. Success is fleeting, but your reputation for being a grounded, decent person? That’s what actually sticks.
