Thank you for sharing this insightful post. Indeed, many books overlook the fact that productivity is not an intrinsic aspect of human nature. Rather, it's a concept largely cultivated by modern society, especially under capitalism. These books often promote the idea of creating a 'superhuman' whose every moment is meticulously planned and oriented towards achieving lofty goals. However, this is not always realistic. People often observe the lives of others and aspire to become millionaires or billionaires, but they tend to forget that success is not solely the result of hard work. The environment and luck also play significant roles in determining one's achievements.
