Re: New dojo/new student
My suggestion would be to consider the following:
Relax - Breathe - and take things slow.
Your students will be as anxious as you will about being a "first class". Stay calm and show them the inner peace that aikido can offer. Remember, the first class will set the tone for following classes, and the dojo's reputation. If you start flashy, they will expect this every class.
Best of luck! Let us know how it turned out.
