fault. It’s like looking at the tiled (铺瓦的) ceiling and concentrating on the space where one tile is   1

what your missing tile is, explore whether acquiring it will   4   make you happy. Then do one of the
three things: get it, replace it with a different   5  , or forget about it and   6   the tiles in your life that

meaning can help us to feel happier. We   17   a spiritual faith, or a philosophy, it should   18   this truth:
if you choose to find the   19   in every situation, you will be blessed, and if you choose to find the awful,
you will be cursed. As with happiness itself, this is   20   your decision to make.
