One movie I come back to time and again is 'The Hustler.' I don't think there's better dialogue in any film.
“Making a million dollars is the simplest thing in the world. Just find a product that sells for $2,000 and that you can buy at a cost of $1,000, and sell a thousand of them.”
“The fear of death follows from the fear of life. A man who lives fully is prepared to die at any time.”
