Hey good question man. I try to stay as positive as possible...I keep myself aware that not EVERY show is going to be GREAT. People will always be amazed and like the magic but try to evaluate yourself as a magician but also the audience as an audience. I also try to be "me" as much as I can when I perform because that is how you will be most effective performing. So , when you are walking around being the "not performer" (regular guy) think how you can be that guy while you perform and try to be as "you" as possible when doing your magic, mentalism or what have you. I notice that if you are genuine people will like you and people will like your magic....unless they are evil
Good food for thought type question.
