Consider branching out into other forms of magic. You will find that when you are performing, the audience will want to see more than just a bunch of card tricks. You should deffinatly start learning coin magic. I strongly believe that there is not book, not even RRTCM, that is more valuable to the magician than Modern Coin Magic by J.B. Bobo. I say this because much of what you learn in Bobo's book can be applied to almost any small object. Bobo's comes with a complete guide to sleeving technique (anyone into close up magic should be exceptionally good at sleeving), different concilments that can be aplied to countless items other than coins, many different methods of doing a retention vanish (I challange you to find a small object that could not be vanished by one of the methods in the book) and
much more. For example, whenever I do a sponge ball performance, I get huge reactions, and all of the sleights I use come from Bobo's Modern Coin Magic. Once you have become skilled with this book, you won't need to carry anything around with you (though I never leave the house without my trusty Bikes

). You will be able to look pick up or borrow pretty much any small object, and amaze your audience. In my mind, one of the strongest effects a performer can perform is picking something up that he has never handled or seen before and performing an amazing effect with it. This is what Bobo's will allow you to do (by the way, I haven't even mentioned how much Bobo's will help your coin magic).
It would also be worth while to look into getting 13 Steps to Mentalism and On the Spot by Greg Wilson (assuming the store you are buying from sells these).
