"Grandmothers and uncles, priests and rabbis, taxi drivers, bartenders, motivational speakers; they all have something to say about happiness. But they don't all say the same thing. And that's where science comes in. By using scientific methods to identify the causes of human happiness we're learning that the secret of happiness was never very secret.
We're connected to each other.
Be long to each other.
We're made for each other.
Life is a journey through time and happiness is what happens when we make that journey together."
