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.

If you’re a solo, Who Not How is a must-read
Format: Kindle
If you’re starting out as a solo, whether you’re a writer a lawyer a consultant, or whatever, Who Not How may be the most important book you can read if you want to have both a successful business and a successful life. Here’s why I think that’s true.
Most people who go solo don’t start their business with bales of venture capital. Instead, we fund those first lean weeks or years with credit cards, second mortgages, and the forbearance of our friends. We’re lean by necessity.
Naturally, in the beginning, we do just about everything ourselves. That’s good and necessary, but it can create a bad habit that’s reinforced by society.
American culture lauds individual achievement. In school, we’re graded individually. The virtue of self-reliance is high on our list. The problem is that to grow and prosper we need to break that habit of “self-reliance at any price” and quit trying to do it all.
When we face a new challenge, the need for a new website, for example, we naturally ask, “how can I do this?” We spend time climbing a learning curve to get to an acceptable level of performance. Asking, “who could help me with this” or who can do this for me” can make our businesses more successful and our life more satisfying. Let me share two examples from my business.
I have a virtual assistant. Her name is Brenda, and she does a variety of administrative tasks that I used to do myself. She does them better, more consistently, and more efficiently than I would. And the fact that she does them frees me up to do the things I do best and contribute most to the success of my business.
Another example. For years I did my bookkeeping. I learned bookkeeping for the first job I got after I left the Marines. I did OK with a paper-based system. But I decided that I wanted to take advantage of what technology had made possible, so I bought QuickBooks. First, I tried to master it. The bookkeeping part wasn’t a problem. But learning about and implementing the automated functions of the program frustrated me.
When I realized what was happening, I engaged a QuickBooks consultant to help me set the program up and review my books every quarter. The result: I used to spend frustrating hours not getting things quite right. Now, I spend about 15 minutes a day and an hour at the end of the month on my accounting.
Both Brenda and my QuickBooks consultant do things that I’m capable of. But they do them better, and, because they do them, I have more time and bandwidth to spend on coaching people as they write their books. That’s what I’m good at and what I get paid for. And using others for those tasks frees up time for me to spend on recreation, recovery, and relationships. Those things make life sweet.
If you’re a solo, that’s why you should buy Who Not How, read it, and put it to work. I suggest you buy the audio version, even if you also buy a print or ebook version. The audio version has some interviews with Dan Sullivan that don’t appear in the other versions. They will add value to your experience.
In a Nutshell
If you’re a solo, buy Who Not How: The Formula to Achieve Bigger Goals Through Accelerating Teamwork by Dan Sullivan and Benjamin Hardy Then read it and put the book’s lessons to work.

A soulful journey that blends adventure with spiritual wisdom
This book is part travelogue, part spiritual quest, and it kept me intrigued from start to finish. Paulo Coelho takes you along on his pilgrimage through Spain’s Camino de Santiago, sharing not only the physical challenges of the journey but also the inner lessons about faith, discipline, and self-discovery.
The writing is simple yet thought-provoking, with moments that feel both mystical and deeply human. I found myself pausing often to reflect on his insights, this isn’t a quick read but one to savor slowly.
The paperback is a nice, portable size with clear print, making it easy to take along or mark favorite passages. For anyone interested in spiritual growth, adventure, or reflective storytelling, this book feels both timeless and inspiring.
Pro Tip: Keep a journal nearby, so many passages spark personal reflection that you’ll want to write down your own thoughts as you read.
