One of the very few books on Martial Arts which go beyond the "naked" presentation of techniques. Bruce Lee explains tactics - things which help integrate the individual skills into an effective way of fighting. Although there are some "low-level" explanations of the simple kicks and punches (of which the most famous are his lead-hand attack and low-level side kick), the focus is definitely on how to use them in a fight, in response to the actions of your opponent. Reminds me of Musashi's "Book of Five Rings" - I would read one page, then sweat over it for weeks or even months, until the knowledge becomes reflex. As a peculiarity, the round kick is called "hook-kick", but the explanations and the pictures eliminate the possible confusion.
