Every actor has a Zone of Genius. This is the space in which you deliver excellence. You know when you are 'on'. You know when you are 'in the zone'. Take the time to Recognize yours. Knowing, with confidence, where you excel will be immeasurably helpful when life circumstances, casting, rehearsals, call backs, performances, don't go the way you expected. It is not helpful to get down on yourself. You can note what worked, what didn't, and move on. But if you find yourself lingering there, in a negative space, go to what you know. Your zone of Genius is with you.
