Be careful- your brain believes what you tell it- what you say over and over again. If you say you can't do something, you will always feel that you can't do it. It is a self-fulfilling prophecy. The brain hears, "I can't do it," and takes it in. Over time it becomes an ingrained belief. This belief is not rationally true and you are caught up in a negative self-fulfilling prophecy.
Lets get away from absolute, all-or-nothing language, like "always," "never," "cant," or "hate." These words will be believed by the brain and will come back to haunt your life. Break out of the negative self-fulfilling prophecies you are in. Stop telling yourself lies and begin to go neutral and let common sense and rationality replace negative self-fulfilling prophecies.
Opening up your mind to all possibilities is crucial in this process. Stay away from absolutist thinking and believing. What you believe about yourself today may not be the truth. You may be stuck in a negative self-fulfilling prophecy.
