It is impossible to survive in a prolonged state of reality, at least for human beings. We spend a good part of our lives dreaming, especially when we're awake.
But there is a process that happens when you're making something, be it a musical or a new play. That process takes time, and mistakes will be made along the way, and you will go down and hit dead ends. But it is so public now. Any yahoo with a computer can start a firestorm.
