How Do You Know If You’re a Good Leader?

The hardest performance review is your own

In September of 1862, Abraham Lincoln shut out the world. The Civil War was going badly. Military defeats were piling up. Political factions were tearing at each other. Personally, Lincoln was exhausted and grieving. And instead of giving a speech, issuing a proclamation, or projecting confidence, he wrote something he never intended anyone else to read.

The document was later titled Meditation on the Divine Will. His secretary, John Hay, said it was “not written to be seen of men,” but rather an attempt by Lincoln to wrestle privately with responsibility, doubt, and forces far beyond his control. Hay described it as Lincoln admitting us “into the most secret recesses of his soul.” What Lincoln wrote is striking, not for its certainty, but for its humility.

He acknowledges that both sides of the war claim moral righteousness. He admits that one, or both, could be wrong. He even entertains the possibility that the purpose of the war itself may be different from what any human leader intends. This is not the writing of a man convinced he has everything figured out. It’s the writing of someone painfully aware of the limits of his own understanding. This is not how we usually picture great leadership.

We tend to imagine leaders as confident, decisive, and unwavering. We rarely imagine them alone, questioning their assumptions, doubting their interpretations, or wrestling with the possibility that their best efforts might still fall short of some larger purpose. Yet Lincoln did exactly that, and he did it deliberately. This is where imposter syndrome quietly enters the leadership conversation.

Many leaders interpret self-doubt as evidence they’re failing. They assume that if they were truly good at this job, they wouldn’t feel so uncertain, so conflicted, or so aware of their blind spots. But Lincoln’s example suggests something different: deep introspection is not a leadership flaw, it’s a leadership discipline.

Lincoln didn’t let doubt paralyze him. He didn’t outsource his thinking to slogans or certainty theater. Instead, he created space to reflect before acting. He processed uncertainty privately so he could lead decisively in public. His self-questioning didn’t weaken his leadership; it tempered it. There’s a practical lesson here for modern leaders.

If you feel like you don’t have all the answers, that doesn’t mean you’re a bad leader. It may mean you’re confronting real complexity instead of oversimplifying it. If you feel the weight of responsibility deeply, that’s not imposter syndrome to be eliminated, it’s a signal to build better reflection and feedback loops around yourself.

Lincoln didn’t ask, “Am I confident enough?”
He asked, “Am I being honest with myself?”

That’s a far more useful leadership question. Good leaders don’t silence doubt; they manage it. They don’t confuse certainty with competence. And they don’t mistake introspection for weakness. They use it to sharpen judgment, expand empathy, and avoid the far more dangerous trap of believing they are unquestionably right.

In that sense, feeling unsure may not be a sign that you’re failing as a leader. It may be a sign that you’re taking the role seriously enough to do the hardest work first, the work inside your own head.

That kind of introspection raises a harder question for the rest of us:
How do you actually know if you’re a good leader?

For most of the year, leadership evaluation is something we do to other people. We rate performance. We fill out scorecards. We calibrate. And then, almost as an afterthought, we move on.

This time of year, annual review season, creates a strange asymmetry. Leaders spend weeks assessing others while rarely applying the same rigor to themselves. Yet leadership is one of the few roles where your effectiveness is almost entirely experienced indirectly, through other people.

Which makes self-evaluation both essential and deeply uncomfortable.

Leadership Is Measured From Multiple Angles

One of the biggest mistakes leaders make when evaluating themselves is relying on a single perspective. Leadership doesn’t have a single audience, and it doesn’t have a single scorecard.

There are at least three distinct ways you are being measured, whether you acknowledge them or not.

First, there’s how your boss experiences you. This is managing up. Do you create clarity or noise? Do you surface problems early or hide them until they explode? Are you a source of leverage or a source of surprise?

Second, there’s how your peers experience you. This is managing sideways. Are you someone others trust in moments of ambiguity? Do you collaborate when it’s inconvenient? Do people feel relief or friction when they see your name on a meeting invite?

Third, and most importantly, there’s how your team experiences you. This is managing down. Do people feel safe telling you the truth? Do they understand what “good” looks like? Do they leave interactions with you clearer and more confident, or more confused and guarded?

None of these perspectives alone tells the full story. But together, they form a far more accurate picture of your leadership than your own internal narrative ever will.

Leadership Is About People, Not Perfection

This is where many leaders get stuck. Leadership is a people system, and people are not clean, predictable, or consistent. You can do ten things right and be remembered for the one moment you handled poorly. You can have good intentions and still cause harm. You can grow and still carry old perceptions longer than feels fair. Perfection is not the bar. It never was.

Good leadership isn’t about eliminating flaws. It’s about recognizing them early, taking responsibility for them, and working on them deliberately. The leaders who do the most damage are rarely the ones with shortcomings. They’re the ones who refuse to acknowledge them.

Lincoln didn’t pretend to have certainty he didn’t possess. He confronted his limitations directly. That’s not weakness. That’s maturity.

Practical Advice: How to Evaluate Yourself Honestly

If leadership is experienced from multiple angles and shaped by imperfect humans, then self-evaluation requires more than introspection alone. Do a 360 review, even if no one requires it.

Ask for feedback from your manager, your peers, and your team. Not as a formality, but as a genuine inquiry. Look for patterns, not individual comments. One piece of feedback might be noise. Five similar observations are a signal. And when the feedback comes, there are only two possibilities. Either the feedback is correct, or it isn’t.

If it’s correct, the path is straightforward, if not easy. You acknowledge it. You make a plan. You work on it. You don’t explain it away or soften it with context that arrives too late to matter.

If you don’t think the feedback is correct, the responsibility still doesn’t disappear. Because now you own the perception. Perceptions don’t come from nowhere. Something you did, or failed to do, created it. Arguing about intent doesn’t change impact. Once a perception exists, leadership requires you to address it, not debate it.

This is one of the hardest truths of leadership: once feedback is given, ownership transfers to you.

The Real Test of Leadership

Being a good leader isn’t about being universally liked. It isn’t about having unshakable confidence or perfectly polished answers. And it certainly isn’t about never feeling doubt.

The real test of leadership is whether you are willing to look at yourself with the same honesty you expect from others.

Annual review season shouldn’t just be about scoring people. It should be a reminder to pause, reflect, and ask uncomfortable questions about how you show up in the lives and work of others.

Lincoln’s private meditation wasn’t written to inspire anyone. It was written to steady himself. And yet, it reveals something timeless about leadership: the strongest leaders are not the ones most convinced of their own righteousness, but the ones most committed to self-examination. If you’re wondering whether you’re a good leader, that question alone doesn’t disqualify you. What matters is what you do next.
