Happiness is to revere each moment with a smiling face. Life is an existence and all decisions contribute to development of evolving existence. There is no true right or wrong decision. To err is human, keep on learning from mistakes to evolve & move ahead in life. Forgive self completely taking full ownership & responsibility for own behavior and deeds. Release the guilt, appreciate all events & experiences in life and be grateful for the good things life has offered to stay happy.
