When someone decides to buy something. That decision is driven by impulse. That impulsive buy decision is based on emotions.
Effective communication is often 90% body language, 7 % words and 3% tonality. When you can captivate your listener by telling them a story.
You can hypnotically influence their buying decision by influencing the emotion with the story. Take there emotion on a wild roller coaster ride.
Bring there emotion way up high and then crash it down to the bottom lows. To a point where they feel that there is no hope what so ever.
Then lead them to the solution and rescue them from the bottom pits. They will then be ready to buy with open arms.
