 The number one difference between a bad product manager and outstanding product manager is that outstanding product manager has strong customer empathy. So a good product manager, they love the customer problem and they want to fell in love with that customer so that they're able to solve problems. As we said, product managers are the CEO of product, not just for the look of CEO, you really need to love the customers and love your product. However, bad product managers, they frequently think about themselves, their managers, their leadership, their very self-centered, they always think about how can I get promoted. They might be thinking about, well, I think this should be done this way, but they didn't do enough customer interview to really understand the pain point of those customers.
