Welcome to the world of the surreal.
Enough of the Kindness Part, time for me to roar. . . (you'll get used to it, it's what I do)
If you haven't read
Corinda's 13 Steps to Mentalism and
Annemann's Practical Mental Magic you need to stop where you're at and back up. Mentalism isn't like magic. . . it's not "tricks". When presented properly it can be enough to start a new religion (and has, more than a few times). There are a couple of FREE Resources for you to grab while you're at it. . .
MENTALISM: A Resource & Guide
Learning Cold Reading
The Swami
These 3 PDFs will give you a foundation as well as understanding of some basic tools used in Mentalism. You will likewise find a couple of rather long lists pointing you to other books you will want to invest in when it comes to cultivating your Mentalism skills.
I'm going to assume that you're not just new but young, mainly because of the purchase in question. There are similar effects that can be done without that plastic sleeve and with incredible freedom that you will be able to do just by studying what I share in those 3 booklets. There are other systems that sell for hundreds and even thousands of dollars that deliver the same general effect, even ways by which to make someone else's watch reveal the thought of time... gimmick free.
I'm pointing this out to you so you can take in a deep breath and realize that this is a very big step you're taking and it may be wise to take things slow and learn the foundation material first. It will keep you from wasting tons of cash and better prepare you when it comes to delivering Psi styled effects in a casual and setting.
If you are in fact new to magic there are some other preliminary books you will want to start with, well before you dive into Mentalism; The Mark Wilson and/or Tarbell Course in Magic are item #1 followed by the Bill Tarr NOW YOU SEE IT; NOW YOU DON'T books on slight-of-hand and from there Bobo's Modern Coin Magic and finally The Royal Road to Card Magic (just don't get addicted to card tricks, it's a nasty habit). Then there is Magic & Showmanship, especially if you want to do Mentalism; it's a dry read but packed with very important information.
It will take you a minimum of a year to two years to complete these foundation texts. Then you can come back to Mentalism if you feel that's your real calling. Most will not given what they find in the other aspects of magic as well as their own discovered logic, fears and phobias. . . simply put, very few people can do Mentalism in the manner it was originally designed to be done. . . most will do Mental Magic, which is highly commercial and far more viable than the other. . . it looks more like a "Magic Show" than traditional
Psychic Entertainment does.
Now get out of here and go study. . .
