Life’s greatest asset isn’t money, but yourself. For someone to keep growing their wealth and career, the first step is to invest in themselves—so that their abilities, cognition, and value can continuously appreciate. In youth, you build capability through hard work; in middle age, your height is determined by your choices—choosing the industry, platform, and direction that fit you. At the same time, you need to find a field worth deep, long-term commitment to—like drilling a 1-kilometer-deep well—putting your time into strengthening your professional skills. Real long-term compounding isn’t chasing short-term opportunities; it’s making yourself an irreplaceable professional asset.
