There is no such thing as failure, only feedback. Everything is an learning opportunity to find out what works and what doesn't work. It is important to separate behavior from identity. People already have all the resources they need. NLP teaches how to access these resources at appropriate times and places.
Every behavior is useful in some context.
If one person can do something, other people can learn from that person's success. NLP models excellence. It is possible to discover the components and strategies needed to achieve a particular result and to teach it to anyone else. The messenger never rests until the message is delivered. When there is a symptom or communication, it is important to pay attention.
