Happiness as a business model

I read a really interesting blog on using happiness as a business model. I will post the link in the side bar. Basically what is being said is that people are willing to pay for happiness, that it is a need as well as a want. The pillars of happiness according to the PowerPoint slide show you will see if you follow the link are Autonomy, Competence, Relatedness and Self esteem.
I personally value happiness in my life and life of those I know. So consider, how your will product help create happiness and market from that perspective.
