WILLY: Sure, sure. I am building something with this firm, Ben, and if a man is building something he must be on the right track, musn’t he?
BEN: What are you building? Lay your hand on it. Where is it?
WILLY (hesitantly): That’s true, Linda, there’s nothing.

– Arthur Miller

Death of a Salesman, Act 2. Willy’s imagined scene with his brother Ben shows his insecurity about his success as a salesman. When Ben suggests that Willy has no tangible results of any success he has built with his firm, Willy readily agrees. Willy knows that he has never achieved anything like the success of his brother or his boss Howard.
