In this rare audio interview with Glenn Gould, I noticed he says something which is very important to all of us. As he talks about wearing a business suit as opposed to a suit and tails at 7:22, he goes on to say that he thinks it's a "bad strategy to let yourself think that anything is a special event". He then says "the easiest way to be happy at this business of making music is to treat every concert as if it were a days work of any kind. The more things that you do to indicate this is something special or apart from everyday pursuits, the more likely you are going to succumb to nervous tension". The interviewer doesn't quite get the depth of the statement, but it's obvious to me that Gould knew very much about his psychology while playing.
