The length of time to permanently restructure an old subconscious program has several variables and they are:
1) Age
2) Gender
3) How much physical abuse was used to reinforce your programming
The bottom line is this is the most powerful tool you have for restructuring your subconscious programming. You must decide to what extent you wish to change and how much restructuring you wish to do on your old programming.
Fear and guilt are used on us as children to try to control our behavior. As a result, these two emotional states eventually turn into anger. This is why we start out with guiding you through the process of restructuring these emotional states because they are also the most limiting. What you wish to restructure from there is up to you.
If any emotional state is debilitating to you in any way, you need to restructure it until you control it and it does not control you.
