Sun Yuchen's 8 pieces of advice for young people from 8 years ago:

1. Before the age of 30, do not buy a house, do not buy a car, do not get married, and invest all cash flow into self-improvement.

2. Marriage is the most tightly bound and also the most dangerous partnership system in human history. Most people are not capable of being good partners before the age of 30.

3. Investing in yourself is not about taking a bunch of classes, but rather spending 20% of your time on trial and error, and 80% of your time on reflection.

4. Spend money on the information density of first-tier cities, rather than on mortgage payments in county towns.

5. Treat your social media accounts as equity that can be infinitely leveraged; followers are future cash flow.

6. Financial freedom is not about how much money is in your account, but rather not having to sacrifice emotions, dignity, and attention for money.

7. The sooner you admit your incompetence, the faster you can embark on the path to wealth. Acknowledgment is the first step to change.

8. Compound interest does not only belong to money; health, cognition, and brand also have compound interest curves, provided that you live long enough.
