Well, I don't do that all the time. Usually it is a week or two on, and maybe a month or so off. I got Wendi's confidence CDs which also have her magnetism track. I was also using several Paraliminals at the time. "Confidence" is something that is really hard to quantify. Something like weight loss is really easy to tell whether it is working or not. I usually prefer to do my own work but I like to experiment with other people's tapes once in a while.
Fractionation is a hypnotic induction technique. A hypnotist discovered that each time a person was put into trance he went deeper. Later he discovered that he could induce trance several times in one day and get the same effect as if he hypnotized the person once a day over a period of several days. It was later discovered that if you put someone into trance, take them out again, and put them back in a few times during the same induction it has the same deepening effect. Wendi's method was not earth-shattering or anything. I just liked the way she did it and incorporated it into my inductions.
