Some people think that the key to everything that happens to us, and that our life is the direct result of our beliefs. To some extent they are right. When there are no other elements that interfere, it is our beliefs that lead us to act the way we do... but in reality, this situation rarely occurs.
In general, our subconscious is conditioned by many other elements: emotional blocks, emotional trauma, family loyalties, etc. Therefore, we must change our programming by playing all the pieces, or the belief recording job may fall on deaf ears.
