Having healthy self-esteem will not make you selfish or demanding. It will not make you narcissistic, taking advantage of others for your own gain. Selfish behavior and attention seeking are in fact outward manifestations of inner insecurity and low self-esteem. It will help you experience life more authentically and use your natural intuition as a guide to healthier living. Good self-esteem involves developing a whole new perspective about yourself from one of feeling flawed, anxious, and undeserving to one of feeling okay with your human imperfections, feeling more peaceful and worthy of respect and affection.
