Fourteen years. I'm currently a Nidan. I am actually running a dojo now, with the help of some other senior students of my late Sensei (and more experienced practitioners in our association, TAA).

Like you said in your video, those interested in being the most effective in a sport fight don't get it. But those who get it, really get it.

I wrote a little about picking up and moving on after my Sensei's passing here. The post is well past payout so if you like it, don't waste your upvote - just keep in touch!
