Do Their Eyes Shine?

General Lifestyle
the real metric of leadership

In 2008, an orchestra conductor took a TED stage, played a Chopin prelude, and said something that still unsettles any CEO who hears it.

Benjamin Zander was not a human-resources consultant or a leadership guru. He was the conductor of the Boston Philharmonic Orchestra, and his statement was surgical: “The conductor’s job is not to make a sound. It is to make other people powerful.” Or, in the version that has travelled furthest: a leader’s success is measured by whether the eyes of the people they lead are shining. He wasn’t talking about motivation. He was talking about a metric.

I’ll confess this talk moves me in a way few things do. I am passionate about classical music — not as a decorative hobby, but as the discipline that has taught me best what it really means to lead. An orchestra conductor doesn’t play a single instrument. Their only instrument is the shine in the eyes of eighty musicians who do know how to play. I’ve been convinced for years that this is exactly the metric separating those who command from those who lead — and I don’t conceive of my own life, professional or personal, without making the eyes of those around me shine. If by the end of the day I haven’t managed it with someone, that day wasn’t worth enough.

Seventeen years after that talk, Gallup put a price on the phrase.

The Cost of Dull Eyes

In its State of the Global Workplace: 2025 report, Gallup recorded something that had happened only once in twelve years: global employee engagement fell, from 23% to 21% in a single year. The deterioration wasn’t diffuse — it concentrated where it hurts an organisation most: in middle managers, whose engagement fell from 30% to 27%, with five-point drops among young managers and seven-point drops among female managers.

That fall in engagement cost the world economy $438 billion in lost productivity in a single year. And it adds to a deeper figure Gallup has sustained: chronic disengagement costs the planet $8.9 trillion a year — 9% of global GDP.

Eyes that don’t shine have a cost. And that cost is no longer an HR data point: it’s a bottom-line data point.

Capital That Extracts, Capital That Grows Roots

Zander had a practice that explains the difference. At the start of each course, he automatically gave every student an “A” — on one condition: they had to write a letter explaining who they had become to deserve it. He didn’t lower the standard. He moved it from control to commitment.

That is exactly the line separating an organisation that extracts performance from one that generates it. Capital that extracts demands results and punishes deviation from a place of fear; capital that grows roots defines a frame of possibility and lets people measure themselves against it, with their own identity at stake. The difference isn’t soft. It’s the difference between 21% global engagement and the organisations that, according to that same Gallup, see turnover fall and profitability rise sustainably when engagement soars.

The common good — of the organisation, of the team, of the executive themselves — is not a moral cost subtracted from profit. It is the source of profit. Everything else is short-term accounting disguised as management.

“Whose eyes are shining?” — the question Zander asked himself every night, after conducting.

The Question That Isn’t on Any Dashboard

Zander closed his talk by confessing that, after every concert, he asked himself that question. And that if the answer was no, he then asked who he would be without that shine in others.

It’s an uncomfortable question to bring to a board. But it’s the right one. Not “what was the quarter’s EBITDA?” — the CFO answers that every month. Rather: the people you lead, do they leave the room larger than they entered, or smaller? The purpose your organisation declares in the annual report, does it ignite something in the person who executes it every day, or does it simply administer it until the next sustainability audit?

No ESG ranking measures this. No impact report captures it. But the market, with $8.9 trillion of annual loss, is already pricing the answer.


I don’t know how to conduct an orchestra, but I’ve spent twenty-five years trying to lead organisations with the same question in my head that Zander asked himself as he stepped off the podium. At ImpactCo we’ve turned it into methodology, not just personal conviction: we work on it as a business metric, not an aspiration.
