“I do not mean to suggest that luck per se plays the major part in success, theatrical or otherwise; but I venture to guess that in the grand design of any successful career the element of luck has been a powerful factor. Perhaps luck is too easy a word–too all-inclusive. A sense of timing would be more accurate–or perhaps a quirk of character that enables its fortunate possessor to tread the main path and never swerve from it. Every successful person I have ever known has had it–actor or businessman, writer or politician. It is that instinct or ability to sense and seize the right moment without wavering or playing safe, and without it many gifted people flicker brilliantly and briefly and then fade into oblivion in spite of their undoubted talents.”
Moss Hart, Act One
