I admire Brian Tracy and other motivational speakers like him. The reason is they stress the importance of knowing what to do and, more importantly, what not to do. I have learned much from him and other such speakers from their books.
Unless one falls ill or is asleep, there is no reason not to spend every waking moment observing, thinking and learning. Reading remains the most important source of increasing one's knowledge. I realize that an MBA is not just a degree. It is a course that, if approached correctly, increases one's awareness of the world. It teaches the student that one must always look at the big picture in any issue. Management is a tough task. I am learning this every day. There are some who manage and lead effortlessly. They may or may not even be educated, leave alone an MBA! Yet for most of us, the learning of the task of management becomes easier when studied.
