Happiness and virtue compliment each other, the happiest people have definitely conquered the art of living life in a de-stressed zone. Tranquility of the mind and happiness go hand in hand. It is only when we over commit ourselves to the external that we allow stress, a space to build itself up.
Humans of today have lost themselves to the external world. Meaningless values have gained priority over the true meaningful nuances of life. Chasing material things and living up to the neighbors way of life has become the accepted norm, and living in an anxiety ridden scenario is perhaps considered just "normal".
