What is a good hand-to-hand fighting training curriculum then? Well it is a documented plan that details the subjects of importance in learning and training to achieve its objective.
While elementary schools and universities assume that the mere exposure of students to varieties of experienced professors in their fields of expertise will provide their students with greater chances self learning and future success, many admit later that their schooling was a complete waste of time! The reason is that there was not enough decisive comprehensive guide for what is success in life in a competitive realistic cruel world.
But what you did get from these schools is exposure and drilling to communicate, learning to use your logic! Life is indeed a learning process but why pay someone for intensive studying and drilling your basics where your logic succumbs to unrealistic presentation of your future? There is just not enough thought in the curriculum! Are secrets kept, or it is just that the people that are in the teaching business were never exposed to them, nor they possessed the logic to see them?
