What about the people that already know me as a person- not a performer and are not easy to convince that they're witnessing "magic" ? lol Look, I'm 17 and I've been called the magician (-.-), the dude with fast fingers(-.-) the devil ( lol)! Still how can I get the most out of my audience? How to emplify their expierince? I think my age plays a role in that 9 and i will post a thread about age and magic) but still..
This is one reason I rarely perform for someone first time I meet them. Similarly, I don't mention my work (acting). I don't want to me known as the actor, or the magician, or the mind reader.
These things are an important part of who I am - but they don't dominate my interaction with my friends, and the people that I meet. I dominate my interactions, in the sense that they experience me before they experience magic. "The guy who reads minds" is no more me than "The dude with black hair". I try to only perform after they're comfortable with me - then they discover something else about me. I try to perform as much as I can, but I also keep a mental note on how much I think is too much. I think one indication of that is when people stop referring to you by your name, but by a name that they give you. It's a sign of categorisation in my view.
I want people to be able to refer to me as me, without thinking of what I perform; but also be able to think of that instantly if prompted. I'm me. I'm a (hopefully) interesting, engaging person in my own right. An important aspect of who I am is a psychology buff, entertainer, mind reader, actor, etc. I am these things; but they are not me. I hope that makes sense.
One key to maintaining a good audience is to get this balance right. Personality is such a big part of performance and of audience interaction. I think that being classed as a magician, or any similar thing, if that is their primary way of classifying you, carries a number of stereotypes and expectations. It conditions your audience to respond in a certain way, and as a result, it's difficult to change people.
If, on the other hand, you ensure that people see you and define you according to how you want them to - rather than giving you arbitrary labels - then you have much more control over how your audience behaves because how they behave is a direct function of who you are as a person!
There are many instances of doctors, for example, who make a medical mistake - but the patient who was wronged insisted on suing some other medical professional, but not their own doctor - for the simple reason that they liked their doctor. People treat the people they like better than the people they don't.
Another key is to respect what you do. Many people don't realise the effort, value and respect we give to what we do. That is one sure way to develop an appreciative audience. This is one thing that really helps bring friends in line. If you knew that your friend, a national gymnast, loved gymnastics above all else in life, and had been training since they were 2 - would you try to heckle them during practice? Of course not, and the reason why is that that situation demands respect. The situation is such that it would be a terrible thing in so many ways to call out and try and put them off. The analogy isn't perfect, but respect shows. Respect your magic, it will show to your friends, and they will heckle you less. My friends never heckle me or try to put me off when I perform.
The other key is to make magic meaningful.
