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.

sad moments, and other different mood changes throughout the ...
Format: Paperback
Throughout the story, characters gave me some outside thoughts that a normal book would not, they brought suspense, sad moments, and other different mood changes throughout the book that make this such a good book. Paulo is on a road for a change in life, with Petrus with him, they explore the road to Copenstela that include different feelings while they were on the road. Paulo is on a trip to find his sword but instead he realizes the trip isn't all about the sword, he is on a trip to finding the sword and along the way he rungs into life changing moments that make him forget about the sword and think more of what time of person he is.
There was rarely any weaknesses throughout the book due to the fact that it always had my attention. Unlike other books that just catch people's attention in some chapters, these chapters have suspense, sad moments and epic moments throughout the book not only In some chapters. Chapters were not to long but also were not too short, different characters made huge impacts on the story leading the book to have more than one main character. I found this book to be very easy to word, there really wasn't any words I did not understand or also there was no sentences that I did not understand, I was able to read the book smoothly chapter by chapter leaving the whole book a positive outcome because I understood what was going on. The characters were some times against each other and in some chapters they worked together, this is a book that I know other people may be able to understand unlike other books that have some words or sentences that are sometimes hard to understand.
I highly recommend this book, after reading this book it left me with a great experience giving me a positive look at the author of this book. This book gave different characters the lead on the chapters, it always had my attention and had some twist and turns that I would not be able to find in just any book. In my opinion, this book had rarely any negative points, this reading was always a time I was looking forward to on spending my time on, I know I can go to this author whenever I would like to read a good book that can catch my attention and I know what would be going on.

"The Pilgrimage" is a book that will guide readers on a journey of self-discovery and growth
Format: Kindle
"The Pilgrimage: A Contemporary Quest for Ancient Wisdom" by Paulo Coelho is a powerful and thought-provoking book that takes readers on a journey of self-discovery and spiritual growth. The book is a memoir of the author's pilgrimage on the Road to Santiago, an ancient pilgrimage route in Spain, and it is interspersed with teachings and wisdom from various spiritual traditions.
One of the strengths of the book is Coelho's writing style, which is both poetic and evocative. He describes his journey in a way that is both personal and universal, and his words are filled with wisdom and insight. The author's unique perspective on the pilgrimage, his reflections and observations on the journey, and the people he met along the way make the book a very engaging read.
Another strength of the book is its focus on the importance of the inner journey and the role it plays in personal growth and spiritual development. Coelho provides a fresh perspective on the topic of pilgrimage, and he offers a range of teachings and practices for cultivating self-awareness and inner wisdom.
Overall, "The Pilgrimage" is a valuable and inspiring book that provides a new perspective on the topic of inner journey and pilgrimage. It is a must-read for anyone looking to deepen their understanding of spirituality and personal growth.
I would rate this book 4 out of 5 stars. The book is well written and offers a unique perspective on the topic of pilgrimage and inner journey. However, some readers might find the author's reflections and observations on the journey too personal and subjective.
