Ok. . . I haven't waded through this quagmire but I have gleaned the previous two pages so I get the gist of things, I believe. One issue in particular throwing me in that I know many within Islam that love magic but refuse to learn it because it involves deception. Mohamed Ali used to explain how tricks worked after he'd perform them because of this particular tenet within said tradition. While this is entirely a personal choice, I would encourage you to speak with a few of your religious leaders on this issue before you put a lot of time addressing your questions . . . that is, if you see yourself as a devoted patron of the faith.
Playing Cards Can ALWAYS be Substituted. Within Mentalism you will find a great number of old timers who refuse to use cards in their shows because of a long list of problems they introduce, but you will see them execute classic card routines using everything from matchbook covers & business cards to photos and postcards, so if you have certain card effects you like and wish to work with, find an alternative medium upon which to build the bit. This will certain require you to create a different approach to doing such work, including story-lines, but it would also give you some exclusive bits of magic and so the effort applied will ultimately pay off.
Learning Patter, Showmanship Skills, etc. comes only through direct experience. That means you need to get involved with things that put you into the public eye -- community theater, public speaking . . . if you're still in school get involved with the Drama Department, Debate Team or Improvisation Groups. . .even choir, as someone mentioned earlier, is an excellent source when it comes to learning and developing your voice, a sense of comfort on stage, even diction (which is one of the biggest weaknesses most performers have; they do not speak clearly and in a concise manner).
As has been pointed out (several times) is that you need to sit at least 90% of the stuff you've grabbed up, off to the side. Pick on thing, such as Bobo, and do nothing but study and work with the material in that text for the next 6+ months. Technically speaking there's enough material in Bobo to keep you busy for over a year . . . same goes with resources like the Tarbell Course in Magic, the Bill Tarr "Now You See It; Now You Don't" books on slights, "Magic & Showmanship" and several others, all of which are "introductions to magic" -- foundation material. Contrary to popular opinion, it takes 2-5 years of serious study and experimentation before an individual is remotely ready to perform on a steady "semi-professional" level. That is, IF that person wants to excel in skill level and general working knowledge -- the ability to be able to do magic at the drop of a hat, based on that foundation knowledge and without relying upon this or that gimmick or packet effect but rather, skill and know how.
Your "Chance" to Prove Yourself Started Yesterday. . . you obviously have a desire to learn so look at what you have and start with the most basic resource on hand, augmenting that material as soon as you can with Tarbell or the Mark Wilson Course or the Bill Tarr books mentioned above. . . resources that will give you an understanding in slights that go a bit beyond coins & cards. Get yourself about 5 American half-dollars, a few antique English Penny's and I think it's the Mexican Centavo that's of similar size so that you can get used to the classic coin routines. That means you'll need a couple expanded shells and at least one "Sun & Moon" coin (Copper on one side, Silver on the other) . . . When you're ready bit the bullet and get a set of Fakini Billiard Balls; in my experience these are the best balls to learn ball manipulation with because they have a good weight and a tacky rubber surface. They are most excellent, I would not use anything other if I were to ever go back to traditional magic. I will warn you, these things are about $100.00 a set.
Take your time and learn everything you can when it comes to working with each item. While that can be seen as over-kill, it will empower you when it comes to tailoring routines for yourself and not getting stuck in the rut of using the same methods everyone else uses. . . you will find yourself using a lot of those "generic" methods, but you will also find yourself incorporating lesser known techniques, which will allow your handling to differ in ways that will cause your fellow mage to "blink" -- to see you as being a bit more than a trick hack. . . I'll assume that's what you're after, no?
One Last Note on Performance. . . study footage of other performers, NOT JUST MAGICIANS however. Find at least 3 different performers in 3+ genre of show biz, who inspire you and make you feel elated. Let those people become a template for you when it comes to character and public image. When I was a kid my chief influences were Vincent Price, Danny Kaye, and Donald O'Conner when it came to Movies but I likewise loved Joel Grey, Liza Minnelli, Ann Margret alongside most members of the Rat Pack in that these guys were "Class" entertainers -- multi-talented and sophisticated.
These icons will certainly shift with time but certain one's will always be a constant; the famed "Monster Actors" of the past such as the Chaney's, Karloff, Price and even some of those of more recent times, like Walken have been there and when it comes to magic Blackstone, Richiardi, and Bob Cassidy have paved the way. My point being, find your handful of icons on which to focus and build your character. . . learn to "channel" them when you work.
Best of luck!
