Hypnosis, or imagination, is the perfect tool to help you prepare for an event that is especially stressful. Picture in your mind going to that event. See yourself preparing, experiencing and concluding this stressful event in a relaxed and confident fashion. The mind does not distinguish between the fantasy of a well imagined event and the reality of it. Your mind will accept this event as if you had already accomplished it, thereby easing the pressure. When it comes time for the actual event, your mind will think it is going through it for a second or even third time.
It is possible to reduced stress that leads to any stressful event and to assure a more relaxed and successful outcome.
