Same here

Looking back over the vast chasm of time, you're up against two problems:

1. People from the ages of about 12-30 don't want to be different. That's where the reaction of, "...two of them are blown away and say, dang, awesome. But when they see the others don't like it that much they say: well, it wasn't that good, and ignore me" comes in. They can't admit that they like something that someone else didn't. That's very hard to get around.
2. What I like to think of as "early-onset cynicism". I've seen it all. Nothing blows me away because I am far too cool and above it all. That seems to affect roughly the same age range.

Small children aren't afraid of being different or expressing their own opinions. As people age, they stop caring what other people think. The age group you're likely performing for is a tough crowd. Andrew Musgrave had some excellent advice--you need to know your crowd. What are they interested in? What'll hook their attention? And then there are some poor, benighted souls who just don't like magic. Sometimes you just have to choose to walk away and perform for a more appreciative crowd.

You didn't say how old you are, but if you are a young magician performing at school, I'd recommend entering the talent contest. Even people who usually don't like magic are much more receptive to enjoying themselves at such occasions.

Next time someone says magic is for little kids remind them that David Copperfield has earned over fifty million dollars a year, was engaged to Claudia Schiffer and owns a group of islands in the Bahamas.....
