I'm going to recommend another really excellent, long out of print book by a famous magician:
https://avalonlibrary.net/ebooks/Derren%20Brown%20-%20Pure%2...
It's an absolute gold mine of tips on performance and full of detailed technical explanations of how he did some of his most famous illusions. (and the answer is not NLP or subliminal suggestion or anything he talks about in his patter, most of the time).
