What advice does Teacher Ma have for young people in their twenties?

1. Before 30, don't buy a house, don't buy a car, don't get married. Invest all cash flow into self-improvement and high-growth sectors.
2. Marriage is the closest and most dangerous partnership system in human history. Most people are not capable of being good partners before 30.
3. Investing in yourself isn't about taking a bunch of courses, but about spending 20% of your time on trial and error, and 80% on review and iteration.
4. Spend money on information density in first-tier cities, rather than on mortgage payments in county towns.
5. Treat your social media accounts as infinitely leverageable equity; followers are your future cash flow.
6. Legally earning money is a prerequisite for caring about humanity and changing the world.
7. Financial freedom isn't about how much money you have in your account, but about no longer sacrificing emotions, dignity, and attention for money.
8. The earlier you admit your incompetence, the faster you can embark on the path to wealth. Admission is the first step to change.
9. True high-level leverage combines capital, traffic, and policy; missing any one of these legs means you can never grow big.
10. Compound interest isn't just for money; health, cognition, and branding also have a compounding curve, provided you live long enough.
