What Sits Underneath: The Inner Work That Builds Enduring Leaders and Better Performance

By Dr Glenn Williams

You have felt it.

The moment in a meeting when the smart move and the right move part ways. The pressure to ship before it is ready, hire before you have vetted, agree to something you know is wrong. The quiet question, late at night, of whether the leader you are becoming is the leader you set out to be.

Is leading costing me something it shouldn't?

Modern leadership is loud with frameworks, capabilities, and metrics. But the leaders who endure have all done something that never makes the headlines or the front cover of a book. They have done the inner work.

Drawing on more than thirty years working with senior leaders across forty countries, Dr Glenn Williams shows what character does, and why it is what sustains the leader who lasts.

This book names what sits underneath the leader other people see.

Dr Glenn Williams has led organisations for 35 years, 28 of them as CEO, working across 40 countries. He has spent just as long noticing what most leadership books leave out: performance was never separate from character. It was always built on it.

He has spent years working alongside thousands of leaders, proving the same thing again and again. The ones who last aren't the ones with the best strategy. They're the ones who've done the work nobody else sees.

His first book, When Leaders Are Lost, named the moment when even the strongest leaders lose their way. His latest, What Sits Underneath, names what holds them together long before they get there. He writes for leaders who suspect what he does: that who you are underneath will always outlast what you build on top.
