50. Chain of Happiness
People unhappy cannot make people happy.
And nothing but happiness can make the world a better place.
Thus we place the highest value on our team’s happiness.
We believe our happiness will spread out into the ‘chain of happiness’: our
family’s fortune, our partners’ success, our customers’ satisfaction, and to the
world.
