So who are you if you are not your personality? To think you are a set of assumptions that shape how you interpret and respond to situations and people is an insult to your worth and capabilities.
Our personality spends so much time screening our environment to avoid potential rejection, we forget to look for opportunities to thrive. The thriving has to wait until there is a path where you are safe from all rejections. Given that path does not exist, our goals are left ignored.
Mental health is more about the inner environment and the outer environment being controlled by conditioning, poor coping skills and high stress, and chemical imbalance is a part of that process; the fire between the gas leak and smoke! Yet we hone in on the fire and blame the personality or genetics!
