There are many inspiring definitions of leadership. Here's an honest one: the art of disappointing people at a rate they can handle.
People hold their leaders to high standards. They expect wonderful things to happen quickly, without pain or setbacks—something not even the best leader can deliver consistently. And when leaders fail, whether due to skill, effort, judgment, or just bad luck, they leave their constituents disappointed.
So if you can't avoid disappointing people entirely, the question becomes: how do you manage their expectations?
It comes down to a simple adage: Underpromise and overdeliver.
It's better to do less and fulfill expectations than do more but fall short of them. Despite knowing this truth, the advice is hard to follow, especially for ambitious achievers used to the "aim high" mentality. But it comes down to trust: a smaller promise kept is worth more than a grand promise broken.
Human beings are wired for safety around consistency and predictability. If I can predict your behavior, I know how to work with you. If I can't, you're dangerous. I can't rely on you. I can't count on what you're saying or what you're going to do, which makes me less willing to put you in certain situations or extend trust—because even if it seems like you're going to do one thing, you might end up doing something else.
But here's where things get tricky: let's say you made a promise, a public commitment, but now the outcome is looking in doubt. Do you say something, or just try your best and hope it works out?
Publicly traded companies have learned to choose the former.
Each quarter, the CEO and CFO provide earnings expectations—how much profit they think they'll generate over the next three months. Analysts at various banks and funds also generate their own forecasts. In the ideal scenario, your company comes in exactly on target or just slightly above.
This is why companies sometimes adjust earnings guidance downward. It hurts in the short term: the market loses confidence, investors sell, the stock drops. But that's still better than showing up on earnings day with a miss and no warning. That's when trust really takes a hit and the drop is much worse.
What really underscores the importance of consistency is that while it's obvious why companies and their executives are punished for falling short of earnings targets, they can also be questioned if they're unexpectedly above.
Why?
Because beating your own expectations by a wide margin signals one of two problems. Either 1) you don't understand your business well enough to forecast it accurately. You genuinely didn't know this was going to happen. Or 2) you're intentionally lowballing guidance to produce beats.
Either way, if you can't be relied on to communicate when good things will happen, investors question whether you can predict when bad things will. The unpredictability itself, or the intent behind it, becomes a problem regardless of whether the surprise is positive or negative.
The same principle holds true for how we show up as leaders, marketers, and partners.
When we're reliable, when we communicate clearly, when we do what we say we're going to do, people trust us. People believe in us. If they like what we're offering, they can take it to the bank.
I worked with a team whose technical co-founder would commit to a customer deadline, bust their butt, work all night but be unable to finish. They'd either pass out at their desk or grab a few winks then wake up to keep going in the morning.
They had every intention of getting it done. But they didn't, and the deadline silently passed. It was only after the client sent a frustrated query requesting an update and explanation that they got one.
Trust took a massive hit.
What the CTO should have done is tell the CEO, tell the customer, tell the team: "I'm not going to hit this. Here's what happened. Here's a more realistic timeline now that I know more." Because when that communication doesn't happen, trust breaks down in two places—between the CTO and the CEO, and between the company and the customer.
Software engineers know their code will sometimes break, so they build their systems such that when things go awry, there's an error code, an alert, a log that gets filed indicating something went wrong and gives a clue on how to address it. The most insidious errors are silent failures—when things go wrong but the system seems normal and like nothing is amiss. You must not allow yourself to become a silent failure.
Look, it's natural to want to promise more. That's what gets people excited, gets them to work with you in the first place. And in a world like ours, full of influencers and big talkers, it can feel like not promising the world means no one will work with you. But if you can't deliver and you fall short, that trust gets burned.
If you say yes to something now and disappoint them later, that's worse than saying no at the beginning. They just made the ask—they know it might not happen. That's why they're asking.
Here's one way I've been able to thread this disappointment gap in a way that builds credibility without overpromising.
"I wish I could tell/give you [request or commitment the client wanted] but I can't. We might be able to get there but it's not something I can guarantee. What I can say is that if you work with me, you can count on [a more accurate and honest deliverable that I believe in 100%]. Does that work for you?"
This logic is just as true for a customer as it is for your internal team. When you commit to a project deadline for your team and then can't hit it—there's usually a good reason.
You're usually not failing to meet your commitment due to laziness or incompetence: you're probably choosing to focus on something else, like completing another task more thoroughly or addressing an unexpected problem.
You made a decision to deprioritize your original commitment. But the sooner you communicate that—that the original deadline is unlikely to be hit, the reason why, and what the new commitment you're making is—the better. You can re-secure some of that trust if you follow through on the second deadline.
The worst thing to do is communicate nothing.
What this means for you:
Set realistic expectations from the start. It's tempting to promise the moon to win the deal, get the buy-in, or motivate the team. Resist. Promise what you can actually deliver, then work to exceed it. Your reputation is built on a tight connection between what you say and what you do.
Communicate early when things change. The moment you realize you can't meet a commitment, speak up. Not when the deadline arrives. Not when someone asks. Early communication gives people options. Late communication makes everyone look bad.
Explain the why, not just the what. When you need to adjust expectations, people need context. They need to understand what changed, why it changed, and what you're doing about it. This isn't about making excuses, it's about maintaining trust through clarity and understanding. The reason matters.
Follow through on your adjusted commitments. If you miss a deadline and set a new one, that new deadline becomes even more important than the original. Missing it again destroys whatever trust you managed to preserve through early communication. The second promise is your chance to prove that your word still means something.
In short: accuracy builds trust, and trust is the foundation of everything else.
Better to do less and be reliable than to do more and be unpredictable. And when you do fall short, don't be a silent failure. The sooner you communicate, the more trust you preserve for the long term.
