The easiest part is performing. Practice, PR, monetary negotiating...you know the business part of being in a band is no fun at all. It is a necessity.
But it is where the business leads you, the stage, that makes it fun. "Normal" people would never get up on stage to do what we do. But it is what happens to those people when we do what we do. Playing is fun, that is why it is called "play". Once we get on the stage to play, jaws drop and you are no longer human. We become icons. I have had numerous marriage proposals from guys who would not have given me the time of day before seeing me on stage.
Musicians are the cool people on the planet...it's easy.
And like others have said, musicians are a family. Music is the only time I can be one of the boys. I know nothing about football or politics. But get me around anything musical and me and my boys ( and gurls ) can talk all day.
