🏠 Everyday Analogy

Just as a traditional Chinese medicine practitioner observes, listens, asks, and feels the pulse to diagnose an illness, investing requires keen observation of one’s surroundings. Which products are always out of stock at the supermarket you frequent? Which app do you find indispensable? What toys do your children love? These everyday details often reveal the next big winning stock more effectively than Wall Street research reports.
