Remember that your beliefs and thoughts influence your mind and your life, so any expectations you have about your self, your character, your abilities, your goals, and your dreams can and often will come true if you believe they will.
Self-fulfilling prophecy - Wikipedia
A self-fulfilling prophecy is a prediction that comes true at least in part as a result of a person's belief or expectation that said prediction would come true. In the phenomena, people tend to act the way they have been expected to making the expectations come true. Self-fulfilling prophecies are an example of the more general phenomenon of positive feedback loops. A self-fulfilling prophecy can have either negative or positive outcomes. Merely applying a label to someone or something can affect the perception of the person/thing and create a self-fulfilling prophecy.
