The authentic self is the soul made visible. -Sarah Ban Breathnach
Being your authentic self is even more important when dealing with ... yourself. I find that people are not honest with themselves enough. If you do not know where you are how can you plan to become better. If you ignore your shortcomings you cannot change them. This is so important for personal growth. Knowing who you truly are allows you to be aware of how you can handle things in life. Knowing how you cope with life's difficulties is the way that you can help deal with stress. Being your authentic self is an overall step to better holistic well being if you take action.
Being authentic is a great place to start in the journey of better health, well being and less stress.
