"his book series comes off as arrogent and not that helpful"
If you are talking about the book series "BRUCE LEE's Fighting Methods" Volumes 1-4 then you should understand that Bruce Lee did not write these books. The text was written by Mitoshi Uyehara who at the time was the editor-in-chief of Black Belt magazine and a good friend of Bruce Lee.
Lee agreed to pose for the pictures and Uyehara wrote the actual text. This information was passed on by Steve Golden on of the first-generation Bruce Lee students in the LA era.
