"I started to realize that if happiness was all about just you, there’s this invisible cap that occurs in terms of your happiness where we can’t seem to sustain the growth or continue its growth up even higher. So we started to think a little bit differently about happiness. And the conclusion I came to, which is the reason I wrote BIG POTENTIAL, is that I think that happiness, while it is an individual choice, is not just a personal choice; it’s also an interconnected one."
