"The requirements of the theatre are very great--a strong constitution, energy and unflagging purpose, charm of feature, these alone do not necessarily mean anything, and they must not be relied upon as assurances of an easy conquest of the public heart. It is not only a question of fitness for the work, but of long years of most diligent effort to master the technique of the theatre, and to develop whatever of the art instinct we may possess upon the simplest, broadest, and most human lines."
