Just a Dude doing karate
About 15 years ago I attended a seminar with Pat McCarthy Sensei a very well renowned researcher and teacher of martial arts. During the seminar I had a question about a drill, I turned and faced Darren Johnson Sensei (one of Sensei McCarthy’s top guys), I bowed and addressed him as Sensei. He smiled put his hand on my shoulder stating “No need to call me Sensei I am just some Dude doing karate).
This has always stuck with me. I am always put off a bit by those claiming Grand Master, Master, Supreme Master, great Grand Master and so on. My students just call me Mr. Jeff or Sensei, just some “Dude” doing karate.
