I spent 20 years learning this the hard way — through 3 startups, hundreds of hires, and more failures than I like to count. Here's what actually works.

"The best and most practical book for managers I've ever read. I immediately ordered it for all our new managers."

What managers say

Leaders at top companies trust this approach

"I finished it in three days and immediately implemented it in my daily routines. It changed how I run my one-on-ones."

"This wasn't just another management course. It was a real conversation about the things managers actually face every day — the hard conversations, the ambiguity, the impossible decisions."

"We brought Lior in to talk about adaptation and change. The feedback from our leadership team was overwhelmingly positive — everyone said it was the best training we've ever done."

"The book gave me a different perspective on daily management challenges, and practical tools to make better decisions. Full disclosure: Lior managed me in the past — and I still recommend this book to everyone."

"I distributed the book to 60 managers two weeks ago, and received feedback that the book is excellent and exactly what they needed."

"Practical, real, and surprisingly fun to read. I've been managing for years, and I still found new tools inside this book."

"Not just a book — a companion. The kind of thing you re-read before a difficult conversation or when you're struggling with a team member."

"I saw in the book many examples from my first management role — conflicts, stories I experienced, questions that came up. I'm sure this book will make all of us better."

"Every manager should read this book. It's the kind of wisdom you usually only get after making the mistakes yourself — Lior saves you the trouble."

Building a career in a changing world

The old playbook was: get a degree, climb the ladder, retire. That playbook is dead. Here's what's replacing it — and how to navigate it.

The person behind Adaptation

Meet Lior Frenkel

Electronics engineer turned philosopher turned entrepreneur. 3 startups (2 acquired), 5 books (3 bestsellers), and a TEDx talk with 415K+ views.
