“The only thing that has to be perfect is your confidence.” — Rod Ben Zeev, 8th November 2014, Barcelona (ES)
In solo scenes, but perhaps everywhere else too, the audience doesn’t want to see you fail. They of course enjoy your struggle, but in the end will feel uncomfortable if you don’t radiate absolute confidence in what you’re doing.
Be confident, and everything else will follow. It’s a question of trusting in yourself, of course.
