I was tormented by bloating all morning, probably from eating too much fiber last night. Some medication helped a bit. It made me think about a question I've pondered repeatedly: happiness isn't an absolute concept, but a relative one. When I was younger, I was terrified of mediocrity and boredom. I not only pursued achievement but sometimes even deliberately sought out danger and excitement. I remember talking to a friend from a privileged background. His family company was in big trouble, his father was imprisoned, and he was forced to be summoned and investigated by the authorities in Beijing at any time. He told me that once this mess was resolved, he felt that having something to do every day, leisurely enjoying a cup of coffee in the afternoon, would be quite nice. I felt the same way. Happiness is simply being able to eat well, sleep well, and have regular bowel movements; being safe and sound with your family, and not worrying about basic necessities. If you have a small hobby, a small business to pursue, and can experience a moment of flow every day, that's even better. What could you trade for that? Sudden wealth, but living in constant fear, unable to sleep or eat well, even taking risks? No need. Maintain a safety net. Whether it's investing or speculating, don't let it jeopardize your own and your family's most ordinary happiness; that's the most important thing.
