Words have far more power than most people understand. Words can make people do things that they may not really want to do yet with just a few simple words applied in the right way a person can buy something they don’t really want or be made to do something that they really don’t want to do.
The power that resides in words is unbelievable and, even when you’re obeying some powerful words, you won’t realise what you’re doing for some words act at a subconscious level where you won’t even notice them. Other words do act at a far more conscious level and some words influence you simply because they are sharp, short and yelled at you rather than whispered sweetly in your ear.
Ironically some of those powerful words can have the same impact whether they are shouted or whispered and you will obey even though it may not be what you want to do.
