Our beliefs are a very powerful force that determines our lives. The experience of many generations proves: if someone is convinced that he can, will do, will overcome, he will definitely succeed. And vice versa. Most people recognize that their beliefs can directly or indirectly affect their health. People professionally involved in health care confirm that for a patient to recover, he must really want it. Is it possible to change beliefs - reject old ones and accept new ones? How to do it? Neuro-linguistic programming has armed us with effective techniques that allow us to understand the hidden mechanisms of action of beliefs and their systems, and then change them for the benefit of ourselves and others.
