This is the most important job in the world.
Pilots are trained on simulators because to use a real planes with passengers would be too dangerous. Parents have no idea how children are emotionally damaged by their(the parents) actions. Therefore almost need training like pilots in a simulator because this is such an important job. Once again it is all about belief and focus.
Children learn by example and it gets passed down from one generation to another. The grandmother could not handle strong, negative emotions, so when her daughter threw tantrums she gave in. She was training her daughter to be negative and depressed. Eventually the daughter could not work because she could not handle stress either, and now she is doing the same thing with her own daughter – who throws tantrums and also gets stressed easily. All three have massive mood swings because they have never learned how to control their emotions.
