I first began training in JKD when I was 16. I'm in my late thirties now.
It's been a real evolution of sorts also through the years. I've gone from being a Jun Fan guy to having almost dropped all of the Jun Fan (wing chun) curriculum.
Is it still JKD? Of course it is as I still adhere steadfast to the underlying philosophy and concepts.
It's been an amazing journey of discovery and I believe that's exactly what Lee wanted for his followers.
