I actually started as a model builder and quickly progressed into production design which made sense because I could draw and paint. But I kept watching that guy over there who was moving the actors around and setting up the shots.
I was probably more scared of my high school exams than I was of the Oscars. At the time you think it's everything and if you don't do well your life's over. Opportunities are gone. So the more you do it the less the fear is present.
