One of the things that frustrates me is when people say that they aren’t creative, or that all the good ideas have been had (for a specific trick). Those are both excuses for being lazy. Creativity takes work, it’s not something that magically pops into your head.
Here’s a good example of something new within something old. Bob Sheets has a great move he uses in the Three Shell Game. That’s a trick that’s virtually unchanged since it was created. However, Bob created the “Sheets Aquitment” which I think is revolutionary.
Many years ago I came up with a move for the shell game that uses a finger ring:
While not as earthshaking as Bob’s move, it is still something new for the shell game. My advice is to keep plugging away with whatever trick you love and you’ll eventually leave your mark on it!
