1. Investment - no trading or speculation:

Trading leads to undue mistakes. First, traders strip themselves of the market's greatest gift: compound interest through income, cash flow, and dividends. Second, traders will likely run into stalwarts: high-frequency algorithms, artificial intelligence-driven hedge funds, and professional traders, etc. bet all your life savings on a tennis match with Roger Federer, why would you bet your savings on the stock traders?

2. Maintain flexibility and openness in terms of investment types:

We must constantly challenge ourselves and expand through different types of investments, if possible.

3. Buy at a low level:

"Buy at maximum pessimism", is a critical factor for successful investment. Fear and bear market is what we need to make a profit. Everyone can win in a bull market, and investor returns will be determined by their behavior in a bear market.

4. Buy for value, not market trends or economic prospects:

Having passive income streams, cash flows and dividends will help us build wealth, not guess market moves or economic results. Numerous studies have shown that choosing companies that can generate increased revenue and income can still help us make a profit even in times of recession.

5. Make a reasonable and reasonable diversification:

As Sir John once said, "Investors who don't diversify are always 100% right."

6. Always learn:

In today's digital age, educating yourself is a must, if you don't have the knowledge to invest or choose stocks, you won't win the market!

7. Don't panic:

If you sell your portfolio just out of panic then you have proven that you are not a good market timing person. Remember The Rule: Focus on the long term and try to buy rather than short. During the 1987 stock market crisis, Sir John was elated, declaring that buying his "stock" would yield "for many years to come". And the truth proves that the decision was correct

8. Learn from your mistakes:

All investors make mistakes and they have to take something out of them. Every investment mistake should be seen as an opportunity for improvement, and it is important to learn the lesson and move on. Whenever I see Sir John making a mistake in his investment, his attitude never changes, and he moves on to the next idea. That is a powerful example of the trading psychology that we should all learn from!
