The Master Key System teaches us that all our circumstances in life are triggered in our subconscious mind.
Until we discover this fact, we operate our life like « junkies » : we are fully addict to all the behaviors and believes ingrained in our « subby »!
This is why most people are always successful in some areas of their life (eg. Health and family) and always fail in others (eg. Money, occupation).
A better way to operate our life is by consciously creating new demands (eg. having a new house, becoming a great musician) in our imagination, then by keeping our attention focused on them until the subconscious mind hears them and start working 24/7 to manifest them.
The best operators are repeating their demands daily outloud because the subconscious mind is 100% responsive to our voice charged with emotion !
