It is said that the brain is the "great architect" that constructs reality. So, if we trust ourselves, we have made the great first step to accomplishing something.
Our possibilities depend on our mentality. But as I said, that is the first step. Because after a positive mentality, we need to prepare practice, do it, and being perseverant in our efforts. It is a matter of thinking, believing, and doing.
