So EVERYTHING you have EVER performed is from your own fertile head?
In a word, yes.
When I started, I didn't know that people published methods. It didn't even occur to me to look for magic on the internet until just over a year ago. When I decided I wanted to do mentalism, although I called it mind-reading then, I assumed I'd have to sit down an create all my own methods. So I did.
My first act was a double act. A polish guy from my university was presented as a psychic from Eastern Europe. I would collect folded billets with questions written on them by members of the audience and tape the billet to a board with the questioner's name written above it. Once 5 questions were on the board, I turn to Pavel and say it a loud voice, "What is the answer to Steve's question?" He would think and then give the answer. I'd take Steve's billet from the board and had it to a spectator who would open it and read out the question.
Going into the audience I'd hand a spectator a piece of paper and a pen, with a book to lean on and ask them to draw any animal or object while I looked away. They then screwed up the paper into a ball and held it tight in their fist. I would go back on stage and ask Pavel to concentrate on the image. He would and then draw something on a piece of paper. The spectator would then be asked to throw the ball of paper to anyone in the audience. Whoever caught the paper, opened it up and when Pavel turned his drawing around, confirmed they were the same.
A spectator who considered themselves good at scrabble was invited on stage while I went into the audience. Going up to various people I got them to write any letter onto the pad. After seven spectators had each put down a letter, I ripped of the sheet of paper and threw it to the guy on stage. He then made the highest scoring word he could with the letters. The audience were then told that before the show Pavel had mentally reached into a bag of scrabble tiles and selected seven. He then came up with the highest scoring word he could.
I would ask Pavel if he had the same word as the spectator (who up until now has not revealed his word to anyone) and he would reply "NO! He has chosen ___________ but _____________ is a highest scoring word with those letters."
Since that act, which was pretty crude, I have read Annemann and Corinda and obviously learnt some new techniques. For instance, a better way of forcing the letters for the scrabble routine. I've also read Max Maven, Bob Cassidy, Larry Becker, Banachek, Ted Lesley, Luke Jermay, Derren Brown, Andy Nyman and others. What I've learnt is that mentalism involves a handful of simple techniques and a interesting idea. Although I enjoy reading the work of others, I don't ever perform other people's material - but with two exceptions. If someone asks me what Cassidy effects I like, or what effects I like from Max Maven, etc. etc. I will peform that effect for someone. And I do some card tricks for fun based on one's I've read in books bought from Waterstones.
