Dan Sullivan’s book “Who Not How” is a transformative guide that redefines the way we approach challenges and goals. Rather than asking “How can I do this?” the book challenges readers to ask, “Who can help me achieve this?” This shift in thinking opens up the potential for exponential growth, efficiency, and success. Sullivan’s core premise is that the path to achieving your ambitions isn’t about taking on everything yourself but rather identifying the right people who can help you get there. This insight is particularly valuable for those who find themselves caught in a cycle of overwork and frustration when trying to handle every aspect of their projects or responsibilities alone. Although, the main idea of the book is inspiring and powerful, the book does come across as promotion of Sullivan’s Strategic Coach program, which might be off-putting for some readers. While the book is relatively short, it still feels somewhat wordy and could have been more concise. Many chapters follow a predictable pattern: a story about Mr. X who faced a challenge, found a “Who,” achieved success, and then helped the “Who” in return. This repetition can make the narrative feel formulaic at times. Additionally, there are numerous one-liners throughout the book that seem disconnected from the surrounding text. While these sentences are mostly quotable, their placement can feel abrupt and unrelated to the passage before or after. Despite these critiques, the book is filled with examples that showcase how leaders and entrepreneurs have leveraged this mindset. By engaging with the right “Who,” you not only save time and energy but also unlock a level of creativity and collaboration that propels your goals further than you could imagine on your own. For readers seeking to achieve more while doing less, Sullivan’s book is a great read. It offers a liberating perspective that not only boosts productivity but also enhances personal fulfillment by allowing you to focus on what you do best and rely on others for the rest. I would rate it 4/5 for its mostly thought-provoking content.

The Goto Resource for every Leader

Format: Kindle

The title says it all — Who Not How — and the content brings it to life. At its core, this book reminds us that our greatest calling is rooted in relationships. It’s also where our greatest assets are found. We don’t need to do everything ourselves—we need Whos in our lives, and we need to be a Who in the lives of others. This is a must-have resource for every leader.

An important book to read, and whose concepts MUSTbe put into practice

Format: Kindle

As an admirer of the work that Dan Sullivan and Benjamin Hardy have done individually, I was sure that a collaboration, two “whos” getting together, would be a good hit. And a good it it is! The issue with these kind of books is what happens immediately after one has finished reading them. The issue is to put things into practice, and change the way we do things. This requires thinking, and thinking is hard, and in most cases we do NOT dedicate time to thinking, so the concepts slide into the past, and no change happens. Time for me, and everyone, to change this default state. This review is just the start of a written reflection, a “thinking on paper” exercise, like my friend and great thinker Jean Moroney calls it. For me, it’s time to shift to my journal. For you, dear readers, it’s time to get this book and read it. Make Dan and Ben your “whos”. Now.
