As a speculator I learned to take the best from books and ideas without arguments (many readers seem to be training to be shallow critics)--good insights are hard to come by. One does not find these in the writings of a journalist. There are some things personal to the author that might be uninteresting to some, but I take the package. The man is one of the greatest traders in history. There are a few jewels in there.

The man did it. I'd rather listen to him than read better written but hollow prose from some journalist-writer.

Jeff Boss is a former Navy SEAL and knows everything about mental fortitude, and controlling your emotions and impulses in the face of critical situations. He uses his expertise in this book to teach others how to develop resilience and fortitude and cope with difficult situations.

Resilience and fortitude are two key qualities of a successful leader, especially when faced with crisis situations or making tough decisions. This book is a great aid in such moments, when you feel unsure of yourself.

The funny thing is that the books that had the biggest impact (like my Verne’s favourite) are not necessarily the best books, objectively speaking. They were good enough to present a new worldview that I was not aware of. Timing probably was more important than their intrinsic literary qualities. They “managed” to fall into my lap at the right time. Such a book was Robert Kiyosaki’s “Rich Dad Poor Dad”, a mediocre book by my standards of today, but deeply inspirational by the ones from yesterday.

Here’s a few books I recommend (in this order) on learning how to write effective copy:

• The Boron Letters by Gary Halbert;
• Advertising Secrets of the Written Word by Joseph Sugerman;
• Kickass Writing Secrets of a Marketing Rebel by John Carlton.

I read this book at a time when Udemy was rapidly growing—over the 18 months where we went from 30 to 200 people. It was helpful to read about Horowitz's challenges, worries, and triumphs when addressing the same types of issues at a similar stage of growth. There are so many big decisions you need to make where there's just no clear-cut, right or wrong answer. There are a lot of gray areas. You gather information from your team, but the hard decisions rest with you. This book helped me realize that while I needed to carefully and objectively consider feedback, I was responsible for making a decision in the end—even when it was an unpopular one.
