I believe that happy life is about inner satisfaction. Two persons having same life pattern can have different view about their happy life because of their inner satisfaction. While inner satisfaction came from religious followings.

Truth, honesty, integrity, love, loyalty, wisdom, peace, compassion, tolerance, patience, humour, joy and freedom are required to live a life of happiness. An expression of happiness is one where you attempt to make others and yourself truly happy. You always know when to you have been successful in your attempt because you experience a good feeling and inner glow. It can be achieved through kindness, a helping hand to a person who is down and out. When your heart is filled with compassion, you quitely bring about changes in your life and in the lives of people around you. To deny happiness is to deny life itself. To experience hapiness, you have to be able to get along with yourself and your private thoughts. Be happy and keep others happy is the key to a successful life.

I think that happiness is not an art, just the result of removing stressors contrary to our existence. The removal of stressors is the art. Joy is the natural state of man.
