Hi, I just began my journey. I hope to get a shodan and begin teaching Aikido. Since I have began learning Aikido, I have used it in the streets in my role as a Police Officer, and it IS an effective tool for Police Officers, allowing me to subdue a resistant subject without resorting to pepper spray or a Taser. I have learned a great deal about myself in the few months since I began.
There ya go fella, so you know it works then, Blooming glad to hear it!!
Best of luck to you and as you know when you get to shodan, in the lovely words of that Carpenters song.... "It's only just begun"
Work hard and you will reap the benefits....
Take care out there...
