A good leader must set rules and regulations in order to establish a strong foundation. Students need the structure that only rules and regulations can give. The instructor must choose rules and regulations that will establish him/her as the leader.
A successful leader is the person who is a living model. In order to set yourself as a mentor, it is essential that you follow the same rules and regulations you expect your students to and monitor their compliance.
Retention can only come when students have structure and feel their instructor expects nothing less than their compliance and success.
