当你经历生活给我们所有人带来的挫折时，改变你对自己说的那些破坏性的话是乐观的核心技能。
Changing the destructive things you say to yourself when you experience the setbacks that life deals all of us is the central skill of optimism.
晏子春秋
The best and most beautiful things in the world cannot be seen or even touched - they must be felt with the heart.
Sometimes we get sad about things and we don’t like to tell other people that we are sad about them.
有时我们会为某些事情感到悲伤，而我们不愿意告诉别人我们为此感到悲伤。
