One gains the most self-esteem by taking responsibility for oneself and learning by your actions. This is further developed through recognizing how valuable to others one really is, through one's service and living their life. Thus, we serve ourselves when we serve others. Each of our own individualities serve to influence and shape our styles and approaches of expression. Your true actions, rather than your thoughts, tend to shape your sense of yourself.
Many thoughts appear, yet few get converted into action.
Quality actions reinforced by good feelings contribute directly towards your health. It is a state whereby the life-processes proceed in the body with optimal functioning and harmony. It is more than merely the absence of disease. It has much to do with the quality of your life. You need quality in your life to truly thrive.
