As a product manager, direct customer contact is crucial in tapping into their energy reserve, providing firsthand empathy and validation of convictions. This can be achieved through regular calls, usability tests, or even just observing customers' behaviors. Prioritizing time effectively to get frequent jolts of direct customer contact can help energize a PM. However, it's also important to take energy from the middle of projects, not just the beginning and end, by finding moments like scoping, where constraints can be used to make progress and drive forward. Additionally, shipping products should be accompanied by learning and gaining new confidence in what to do next, even if it means throwing out previous work. By recognizing these sources of energy, product managers can boost their motivation and drive innovation.
