Being on stage is a seductive lifestyle. My advice to aspiring actors is think twice. People sometimes go into acting for the wrong reasons - as a shortcut to fame and fortune. If these goals are not attained, they feel a bitter disappointment.
Unfortunately, when you're an actor you have to act. It's not like you can sit in your living room, your bedroom, your study or whatever and act with yourself. It requires having somebody to respond to.
Acting should be an end in itself.
As an actor, we are, in a way, a mirror of other people.
