This quote suggests that what we think about often can become a reality in our lives, even if it is not something we are directly aware of. Our subconscious minds are unaware of what is a joke and what is reality, so whatever we think of often, it will become part of our reality. This means that if we are constantly thinking negative thoughts, they might manifest in our lives. In contrast, if we focus on positive and uplifting thoughts, they can also become part of our lives. Therefore, it is important to bring awareness to our thoughts and “choose” which ones we are comfortable having as part of our lives.
