For me JKD(I dont practice it so I dont really think I can talk about it) meant making your own style by following multiple. Take that which is usefull and throw away that which is useless was a quote I take to heart.

Create your own path and rules. Learning how to fight can only really be done by experience in my opinion. There will always be things you cant predict. Brucy(lol) was a brawler, and he became a martial artist. He HAD experience.

So JKD to me, is creating your own path...

how you want to do that is up to you.
