“I'm not an expert, but I want to be.”

Ben Nicholson

Successful people acquire work oriented and highly specialized knowledge, and they rarely if ever acquire generalist knowledge. They are expert in one specific discipline. They read, try, and learn a lot in their specific field of work. You should read every book, watch every video, and study every expert in your work field (or the field in which you want to be an expert).Highly successful people e.g. Warren Buffet, Elon Musk, Bill Gates and Mark Cuban read all the books about their work field while still in college. So you should all books about your work-field, because any book you left may be the book you need most.
