The Golden Rules of Magic
1. Never reveal the secret of an effect
You are more popular as a magician when the audience does not know how it is done. There is simply no benefit or gain in sharing the secret, in fact it kills the magic and you will not be able to perform the effect again to the same audience.
2. Never repeat a trick to the same audience
Repetition forces the audience to concentrate on the method, not the effect of the magic, and the performance is lost.
3. Practice. Practice. Practice.
Make sure you know what you are going to do and what you are going to say before showing a trick. Practice your moves and rehearse your routine. Do this in front of a mirror, or use a video camera as you will see exactly what the audience sees, and hears. Practice refers to repeating individual moves over and over again until flawless. Rehearsing includes using your script and performing your routine non-stop from start to finish.
4. Find your own style
The most natural style is own. Adopting the personality of a magician you saw on TV does not make the magic unique, and in many cases makes the audience uncomfortable.
5. Have fun
If you are enjoying the magic, the spectators will too. Part of having fun is being confident in your routine (including patter and misdirection) and that comes from practice.
6. End on a high
Several strong effects with a logical progression to a climax guarantees to leave your audience asking for more. That is the best time to end your routine.
