你祈求下雨，你也得处理泥泞。这是其中的一部分。
You pray for rain, you gotta deal with the mud too. That's a part of it.
Happiness in this world, when it comes, comes incidentally. Make it the objet of pursuit, and it leads us a wild-goose chase, and is never attained. Follow some other object, and very possibly we may find that we have cought happiness without dreaming of it.
真相很少是纯粹的，也从不简单。
