There is nothing that serious

No matter how big the issue is today, it will be a small matter tomorrow;
No matter how significant the event is this year, it will be a story next year;
If you encounter something that upsets you,
Tell yourself:
There‘s nothing that serious.
今天再大的事，到了明天就是小事；
今年再大的事，到了明年就是故事；
如果遇到不顺心的事，
对自己说一句：
没什么大不了的事。
