Well, from your training you should have taken what you know and be able to teach it as thoroughly as you know it to a brand new student. Even though you have to treat everyone different because of their abilities, create a plan that you can use every time to start a consistency that will get you in a good teaching groove. From there, you can alter your basic plan to meet the needs of different students. Be yourself, be honest and upfront to students. I have seen many new instuctors who know their stuff, but don't have the guts to give someone the constructive criticism they really need to succeed. Really it comes down to being relaxed and the rest will come over time. Good Luck!!!
