Some surprisingly useful psychology tips:

1. When you feel like someone is watching you but you're not sure, look up at the ceiling or the sky. If they are also watching you, they will subconsciously follow your gaze.
2. In a crowded place, don’t look around aimlessly. Focus on the direction you want to go, and a path will appear before you.
3. When the car in front is moving too slowly and you feel irritated, imagine they are your grandfather. Your anger will mysteriously disappear.
4. Before playing rock-paper-scissors, ask your opponent a complex question. They will get caught up in thinking, making it more likely they will choose scissors next.
5. Emotions influence behavior, and behavior can also influence emotions. When you're feeling down, sit up straight with your head held high; your mood will improve.
6. When lending a pen, remove the cap before handing it over. The other person will be more willing to return it when they’re done.
7. People who can write well are emotionally intelligent and can sense others’ feelings. Strong writing skills make you more visible, recognized, and promoted.
8. When asking a question and the other person only answers halfway, don’t rush to speak. Keep silent and stare at them; they will continue talking.
9. Don’t compare prices when shopping; ask yourself if you really need the item. Sellers often use the “bait effect” to make you lose your rationality.
10. If you’re upset with someone, stare at their forehead while talking. They will feel like they are being interrogated.
11. To make someone like you, ask them questions—even if you already know the answers.
