No just means “not yet”
Charles Bukowski is one of my favourite Americans – alive or dead.
The fact that he was born in Germany is just mere detail and anyway, America could do with a few heroes.
A famous quote attributed to Bukowski “You’ve got to die a few times before you can really live.” could be considered as a real metaphor for selling.
Much emphasis is put on getting the customer to say “yes” when actually the process of influence can only really begin when the customer has said “no” and it is when the customer has said “no’ that the selling process begins in earnest.
The quicker the customer says NO, the better chance there is of finding out what the real problem is.
