When you consider how much of acting is based on images and ideas, the ability to visualize is one of the most important abilities for an actor to develop. And it’s not just that you can see it—it must affect you. It must give you something that feeds your acting. You must live off of it. Maybe it’s the color. Maybe it’s the delicacy. Maybe it’s the strength. Shop … shop … shop until you find what ignites you and brings you to life.
