Everything we perceive in the physical world, such as life, career, family, partner, children, health, etc., is a manifestation of the information in our brains. The information in our brains is the source of everything external. When we want to change our external life, family, career, etc., it is crucial to process the information at the source.
In other words, our thoughts and beliefs create our reality. What we think about and believe in becomes our reality. If we want to change our reality, we need to change our thoughts and beliefs.
