Top 15 Survival Rules for Master Experts:

1. Strengthening yourself is the ultimate solution to all problems. The reason you get sick is because your physique is not strong enough. The reason you are poor is because your mindset is not strong enough.
2. True security comes from being independent and wealthy. Others respect you not because of your kindness, but because of your strength. Fools are emotional; experts are profitable.
3. Maintain emotional stability at all times and don't be affected by bad people or bad things. The strong are calm like water; the weak are irritable and angry.
4. People who don't do well generally have a childish mentality, lacking cultivating thinking, process thinking, time thinking, and long-term thinking. They tend to be anxious, pessimistic, hopeless, and extreme, and are easily exploited. When others say a project can make quick money, they tend to believe it.
5. Do not pity anyone, trust no one, keep no deep relationships, and do not complain to anyone. Keep things hidden, stay calm, do not show off, avoid scheming, be careless about small matters, decisive about big matters, see through but not expose, inner peace and calm, prefer solitude, and avoid flattery and sycophancy.
6. Reject ineffective socializing; associating with the poor or lower-tier people is useless socializing.
7. Don’t value relationships too much; you can live well even without friends.
8. Any relationship that lasts is just an acquaintance; those who care will feel burdened, and those who don't won't care. Love is voluntary; after everything passes, no debts or grudges.
9. Do not have any expectations of anyone; without parents, spouses, siblings, or children, the more you hope, the greater the disappointment. Without hope, there is no disappointment.
10. Do not trust family affection around you; pretend to be poor in front of them and maintain a sense of vanity.
11. Whether you marry or not, you are living alone. Relying on others will inevitably lead to pain and suffering.
12. When it doesn't involve your interests, do not argue with others; let them speak freely.
13. Offending a few people or making a few mistakes is not that terrible. Living your life with concessions and fear is the most frightening.
14. Except for illness, all the pain you feel is caused by your values, not reality. Once your inner peace is achieved, the outside world becomes silent.
15. All resources in the world are yours; you can use them at will. The resources are not owned by you but can serve you. Understanding this, you will be unstoppable.

If you understand these 15 rules, you will realize that the underlying logic of each points to the same thing: human nature.
