When a prospect is not interested then you could pose the "What if" question.

Let's say you sell home security alarm systems and your prospect says,
"I don't need an alarm, I have a dog!"

You could then respond with a "What if" question and say the following:

"What if an intruder knows that you have a dog
prior to their break-in
and then comes prepared to handle your dog?"

Every time you hear an objection
just pose the "What if" question and suggest an alternative scenario
that could make their perceived reality a nightmare situation.
