When you come to see me or any hypnotherapist, there are 2 parts to the session. First, there is a discussion about what the issue is and the change that you desire. Then, at the end of the session, you are hypnotized and the changes that you want are implanted in your subconscious. Very subtle and very powerful.
The current model of the conscious and subconscious mind is that 10 to 12 percent of the mind is the conscious mind and 88 to 90 percent of the mind is the subconscious. If you take a look at this it is easy to see why changing a behavior is so very hard.
Imagine you were driving a car. 88 to 90 percent of the engine was being used to go in reverse and 10 to 12 percent was being used to go forward. How hard would that be to get anywhere at all? Hypnotherapy can help with different techniques to get both parts of your brain working together.
