12 Rules to See Through People's Hearts:
1. People with big mouths usually have shallow personalities and are not suitable for deep friendships.
2. Those who speak less tend to be extreme: either very simple or very profound.
3. People whose emotions are written on their faces usually have good character; those who can control their emotions are definitely not ordinary people.
4. Those who start with "I have a friend who is very capable" often lack abilities themselves.
5. People who dislike bothering others also dislike being bothered; those who don't know how to refuse usually don't understand social interactions.
6. Those who are carefree and don't fit in are often seasoned veterans, while those who feel anxious about not fitting in are usually social novices.
7. To judge a person's character, look at who they promote/recommend.
8. Being overly cautious in work may offend others; a bit of assertiveness can actually earn respect.
9. People who are good at ingratiating themselves should be kept at a distance to avoid being dragged down.
10. A person who seems serious may have a restless inner self.
11. Those who can be in high positions must have exceptional qualities, even if you dislike them.
12. People who quickly recover from relationship failures either didn't invest their true feelings or are frighteningly rational.
