No, you can not teach yourself. It is not safe to rely on things that you may be doing incorrectly, even if you are just learning the kicks and punches for fun (and not for self-defense). You could hyper-extend your knees, wrists, or elbows doing the kicks/punches wrong, and you can easily break a foot or hand striking an object wrong.
Before anyone lambasts me, please consider that Bruce Lee never taught himself. After years of wing-chun, he took what he knew (such as proper, safe kicks and punches) and modified them over the years. Also, he was visiting boxing, karate, and kung-fu schools everywhere, taking little bits and pieces that he liked.
Bottom line is that you need to find a teacher and go to him.
Don't just check out jkd. There are many karate and freestyle schools that look identical to the jkd schools around.
If money is a problem, as it is with most of America, find a boxing school. Most of those are free if you are under 16 years old or so. Also check out your local YMCA, churces, or community centers. Many of the BEST martial arts schools are tucked away in places like that.
How old are you and what general area do you live in?
