You are more than any physical perception or situation. You do not have to try to be more positive, to try to feel better, to try to change what seems to be your current state. Personality and ego are not you. They are conditioned patterns, grounded in illusions of time that are irrelevant.
Notice whether you hear a voice telling you that you are anything less than unlimited, successful, confident and expanding into more. Be aware of the mechanism at work within the mind without allowing it to control you. At your centre, the authentic you feels another perspective. Be that.
