【释义】金属之所以被折断，是因为其太过刚硬了，流水之所以能保全，是因为其柔和；高山之所以被挖掘，是因为其高大，而山谷之所以能安全无事，是因为其低下。【延伸】刚强耿直的人，容易受挫折、遭打击；柔和无争的人，则能够保全自己。刚强的克星，是温柔。

Every person you meet knows an amazing lot about something you know virtually nothing about. Your job is to discover what it is， and it won’t be obvious.

Small actions, when multiplied by millions of users, can change the world.

【译文】不要轻信那些所谓特别正直的人，也要防备那些标榜仁义却不仁义的人。山里有长得笔直的树，世上却无正直的人。

I don't need a reason to be happy. I choose to be.
