1. Never get involved with someone who is superior to you. It will be a fragile relationship. Eventually, that person will realize there is someone better out there for them, disappoint you, and cause you heartbreak.
2. Don't underestimate your opponent. You never know what they're capable of. Whether it's an easy fight or a difficult one, always keep giving it your all.
3. In long-lasting relationships, avoid being overly submissive or controlling. Find your strengths and become dominant in those areas. This creates a win-win situation for both parties.
4. Don't get married just for the sake of getting married. Get married when you are mentally and physically ready. Otherwise, your life will be ruined and your dreams will be shattered before your eyes.
5. You shouldn't do what you're good at for free. When people work for free, they start to take you for granted. Your value is completely lost.
6. Don't laugh at someone's failure. What goes around comes around. When the day comes that you fail (everyone fails once), it's terribly unpleasant when others laugh at you!
7. Don't try to trip others up to win the race. That won't work in the long run. Instead, you should improve your own abilities by working hard and improving your skills. That's what will always make you a winner.
8. Don't try to force your opinions on others. That's just foolish. State your opinion politely and demonstrate how it fits perfectly. People will listen to and follow someone like that.
9. Don't make decisions too early or too late. Decisions made too early have many drawbacks, while decisions made too late cause confusion and lead you down the wrong path.
10. Never treat anyone rudely without reason. It will ruin your character and reputation. It is absolutely not a good thing.
