Instant Hypnosis depends greatly upon thevolunteer The type of induction should be geared to the volunteer An artist or designer have great visualisation skills and therefore would not be good candidates for instant inductions as using their visualisation skills with leading inductions would have the greatest chances of success.
Instant inductions tend to be used for analytical people such as engineers and scientist would spend all there time wondering about the psychological significance of a stair case.
The best instant induction in my humble view is the handclasp induction following some simple suggestability games. The methods can be found in any good hypnosis book. Johnathon chase is brilliant in his books and DVDs.
If all this fail look on the net. But remember "The map is not the territory" just copying the words is not the same. There is so much involved in an induction to be written here. If you are serious about this read and research for your information. Its worth it, but you must be dedicated.
