Whatever we expect with confidence becomes our own self-fulfilling prophecy.
Most people have similar end values, but each of us experience them differently. This is simply because of both major and subtle differences in our beliefs. Beliefs take two forms: Broad generalizations about life, people, and things; and rules we use to measure the worth of our own and others' actions. Rules are more definitive. Rules determine, in our minds, the things and events that must happen in order to experience results in a particular way. Rules take the form of "if, then" statements such as "If I make a million dollars in the market I can quit my job and then I'll be happy" or "If I make a mistake on a trade, then I'll learn from it." All of us have our own unique set of beliefs and rules, and it is this unique set that gives each of us a distinctive personality.
Your beliefs are the ultimate self-fulfilling prophecy. Your subconscious is gullible - it believes what you tell it to believe. If you believe you don't deserve to be successful, it won't let you be successful. If you believe you don't deserve love, it won't let you achieve love. If you believe that you aren't intelligent enough, it will make you stupid. Believe me when I say to each and every one of you, you are intelligent enough!
