Positive emotion is one of the key elements to attaining authentic happiness.

You should work on building positive feeling and character. Gain satisfaction about the past and optimism about the future. Learn how to create happiness in the present and sustain that happiness over time.

You can do this by surrounding yourself by positive people, events, places, things and changing your attitude/worldview about life. Continually renew your signature strengths and virtue.  Most of all, work on your personal satisfaction and love.
