You can’t learn everything in school.
In fact, many of the greatest lessons are found outside of the classroom. As someone that went to graduate school (twice) and did get an MBA, I will not diminish it by saying that reading some books is the equivalent of completing a postgraduate degree. It’s not. I learned a great deal from reading case studies, listening to lectures, and engaging with my fellow students.
However, there there were some gaps that business school did not address.
To fill in those gaps, I turned to books.
