In the early days, this was one of the big attractions to acting. As someone who kept my emotions as close to my chest as I could, I would watch actors let loose and express things I could only imagine, or had only felt the suggestion of.
When I started acting, I often worried about what would happen if I had to play a really angry person. I fully believed that I didn’t get angry, that I didn’t know how to act authentically angry because it wasn’t in me. I got angry onstage long before I felt comfortable enough to express it in my life. Art was my practice in life. And life was my practice in art.
