The gap between experts and porters - the power of learning methods

Learning is a commonplace issue, especially in today's context where Internet technology is iterating faster and faster and competition pressure is increasing. Learning has become an essential skill for "natural selection and avoiding elimination" in the social ecology. Although learning requires methodology, there is no set of learning methods that suits everyone.
