Hey everyone. I have just received my first dan, and since I want to open schools later on in life, my saseong told me that I should start a club and start teaching TKD. Its going to be sort of my own miniature school. Now, I'm very competent in everything i've learned so far, I study my encyclopedia almost every day. But I'm a little worried about sparring. I'm very good at sparring, one of the best in my school, but in the back of my mind I have this bad thought that someone is going to come to my club and we'll spar, and some 6'3'' new student might get the best of me, which would be horrible. To anyone who teaches, have you ever had this thought, and how did you get rid of it?
