The above posters have given you spot-on advice: If you can master everything in Mr. Giobbi's
"Card College" books, all will bow-down to you in abject-deference, to say the least.
Now, please take the rest of this post with a grain of salt, as you would a marginally-obnoxious pep-talk from a grizzled coach--tough, poorly-articulated love it may be: it IS intended with love after all...
While we live in an age in which we can learn a language a month or find over-whelming amounts of information on any conceivable subject at the tap of a button, there are still certain conditions that prevail: it takes TIME to get GOOD at ANYTHING (see Mr. Alexander's posts on the art of cutting silhouettes, for example).
While you may have the base of abilities to "zip up the ladder", or "pass the ABCs" quicker than others and thus get impatient, that is a good sign regarding your talent and tenacity. But you still need to know your ABCs.
You should also know that, as MUCH as you may WANT, I dare say there is WAY more out there than you can imagine, with more piling-up every day--so keep practicing, pal. The fact is, I predict, you're going to feel as if you don't know the real [censored] for a while yet. Sorry.
It's not JUST about dexterity, "finger-flinging", or the practice of physical moves--while vitally important (and the better you can get at all of the above the BETTER) it also involves among other things psychology, timing, scripting, audience-management, stage-craft. It has taken a lot of folks centuries to accumulate the information you now crave. Chill-out and keep practicing, rookie.
Everyone understands that NOT-Everyone can automatically be an N.F.L. Quarterback, or say, win the Boston Marathon with no training. --BUT quite a few assume that if you buy a couple books and/or dvds, and fiddle for a couple months with a pack of cards, you're a magician!! Sorry.
Paul Harris once said (in "Close Up Kinda Guy", if memory serves) "Practice 'till your fingers bleed". It's worth it.
