Everything and everyone has two sides in different proportions. Some seems to more one than other some seems having only one side. This perfect balance make everything and everyone perfect. When I look into mirror, I see two sides of me; dark side and bright side.
It is up to me what I want to see. With self-awareness I see perfection in my past, help me appreciate my present, and remind me how beautiful my future is going to be. I see bright side of everyone and in everything, their brightness help me see my dark side, help me to be more and more thankful and live a full life.
PS: The married couple is like two candles. Too close to showing the shadows which they can not see, if both are thankful to each other their life will be honeymoon. One of them is thankful, his or her life will be heavenly. If none of them are thankful, their lives will be living hell.
