Nai Zi Ge has been learning English for three months now, and I have many reflections:

1. A good teacher is very important. Nai Zi Ge's English teacher is slightly older than my mother, very patient in teaching me English. Singaporeans speak English as their first language, so their English is very good. They can communicate in Mandarin daily, but when it comes to questions about Munger and Buffett, that’s a different story. Besides Mandarin not being very good, my pronunciation, vocabulary, and patience are all strengths. Most importantly, they treat Nai Zi Ge like a child, very patient, often giving him a lollipop or cute pencils, which really touches Nai Zi Ge.
2. For daily life—food, drink, travel, entertainment—communication in English is no problem anymore. Now, Nai Zi Ge goes shopping alone, takes taxis, orders food, goes through customs at the airport—all using English. He can basically express his needs and ideas.
However, for in-depth communication, he still struggles because this is a process of continuously accumulating vocabulary.
3. Learning English based on interests makes it more enjoyable. Nai Zi Ge really wants to understand Buffett and Munger’s Berkshire Hathaway Annual Shareholders Meeting Q&A in pure English. Because he knows the Chinese version, he keeps guessing and trying to understand the English version, which is very interesting—learning about English culture through this process.
4. Actually, Nai Zi Ge wants to discuss many methods of learning English, continuous A/B testing, and so on. But in the end, after some thought, the most important factors are environment, interest, and habits. All of these ultimately boil down to these three core elements.
5. Nai Zi Ge no longer wants to compare himself to anyone, nor does he envy others. Strangely enough, after spending so much time contemplating the seven deadly sins of humanity to solve jealousy, he finally realized that focusing on oneself naturally eliminates envy of others.
