What does happiness actually mean?

All of us want to be happy. What does it mean to be truly happy? What does it take to be truly happy?

I read this excellent article that talks about the work in this area by Emily Esfahani Smith. She has also done a TED Talk on the same topic. 

This article made a lot of sense to me when I look back upon my life and see the effect of the four factors that she talks about - belonging, transcendence, purpose and story telling.
