When it comes to the two key aspects of life—marriage (relationship) and money—one's values are often revealed. While reflecting on marriage brings up many emotions, today I choose to focus on my personal financial journey, presented chronologically:

1. Day trading Taiwan index futures

2. Stock picking in Taiwan (using financial reports), Taiwan real estate (for self-use), passing the CFA exam

3. Swing trading index futures (moving averages + chart patterns), U.S. ETFs (across multiple markets), U.S. bond ETFs (various maturities), U.S. stock picking (financial report-based), Taiwan real estate (self-use)

4. U.S. ETFs (multiple markets), U.S. bond ETFs (various maturities), U.S. stock picking (financial report-based), Taiwan real estate (sold)

5. U.S. ETFs (multiple markets), U.S. bond ETFs (various maturities), Berkshire B shares, Taiwan real estate (self-use)

6. U.S. ETFs (multiple markets), Berkshire B shares, Taiwan real estate (self-use + investment)

7. U.S. ETFs (VTI), Berkshire B shares, Taiwan real estate (self-use + investment)

Future plans:

Stocks: Still focused on U.S. stocks, but with Buffett aging, I’m considering reducing my Berkshire B shares.

Real estate: Plan to reduce my holdings in Taiwan and purchase a residence in the U.S.

Formation of my investment philosophy:

It’s taken 20 years, shifting from short-term to mid- and long-term investing, from focusing on wins and losses to long-term value. Confucius said: “When young, control your temper; when old, control your desires.” I’ve evolved from chasing the holy grail of market laws to using common sense and humanities (politics, culture, history) to judge the market, from seeking complexity to embracing the simplicity of rough but correct principles.

Investing isn’t just about gathering information; it’s about accumulating wisdom. It’s not simply building knowledge but about cultivating personal growth. Investment is an independent pursuit—you make your own choices and take responsibility. It requires long-term learning and deep thinking, making it unsuitable for constant interaction with others, but also not something to be entirely isolated from. After all, investing is a social endeavor.

A successful and happy investor can lead a simple, modest life while being rich in spirit—sighing at human foolishness yet remaining optimistic about civilization's progress. My curiosity about the world of investing has led me on a long journey to understanding human civilization. From youth to middle age, I’ve come to understand myself better and will continue on this path.
