So with JKD or with any of the martial arts for that matter its been said that you can't rush it. Well, it does make sense that a person who works harder and puts more into it is going to learn it faster. For instance, lets say there's a guy who does JKD and he trains three times a week for two hours each time. It makes sense that he will progress and develop knowledge, skill, ability, and technique faster than somebody who only trains once a week for an hour each time. You wouldn't call this rushing it but the person who trains three times a week for two hours each time will no doubt learn it faster.
