I am a 24 year old male. I am currently ranked Blue Belt in Kempo. An older gentleman who once taught self defense in the city is currently sick and he contacted me to take his place. I have no idea why. I fought in MMA for 2 years and I did 5 months of amateur boxing and now I’m currently learning Kempo. The event is next Thursday and they have already posted posters and I’m nervous as hell. This event will last 2 hours. What are some tips that you can give to deal with my nervousness. What are some techniques that are a must to teach?
