The horror many novices face is not knowing that the natural counts much more than the pretention of being somebody else. The more natural you are then the more convincing the interpreted role will be. The horror many professionals face is that pretending to be natural eventually catches up with them.

Most artists would just as soon quit once they become conscious of their exploitation and that is a sign of strength not weakness.
