My long-term project is mastering estimation centre dealing and high-speed deck memorisation. There's still some work to be done to get these techniques to performance standard, but I've been steadily improving, so I'm confident that they are acheivable goals. I'm looking forward to the day when I can take a borrowed deck, spread through it to "check all the cards are there", and then deal any hand called for, produce any four of a kind, change the top card into any named card, make any named card instantly travel to my pocket etc. etc. I reckon these two techniques on their own could produce a full set of mind-boggling magic.
In addition, I'm paying a lot more attention to routining and audience management, making sure that the effects I currently perform have the maximum impact.
