"You want to try and bring a character to life in an honest a way as you possibly can. It doesn't matter whether he's a doctor, an actor, a car salesman or a captain of a starship. If you can bring truth and honesty to that character, then your audience will believe you."
"The salesman knows nothing of what he is selling save that he is charging a great deal too much for it."
"Sales are contingent upon the attitude of the salesman - not the attitude of the prospect."
