When a person is engaged in work for a long time, understanding the logic of doing things and optimizing methods is not solely to improve efficiency; more importantly, it is to achieve goals in a way that makes oneself happier and more sustainable. For example, what I've recently realized: 1. Ambition and confidence need to be substantial (waking up every day with clear goals and drive, without being distracted or unfocused.) 2. Motivation needs to be pure (helping you face the times when goals are not achieved or immediate positive feedback is not available, such as during moments of traffic anxiety, reminding yourself that today's goals have already been accomplished, and that expression is meant to authentically present oneself, not just for the sake of data.) 3. Working on 2-3 related and important tasks simultaneously is easier to create a positive cycle than to stubbornly focus on one task (if one task gets stuck, smoothly switch to another task to keep the energy and knowledge flowing. For example, reading/listening to podcasts can help me work and output; when encountering a bottleneck, I should calm down and read first, establishing a self-consistent cycle in terms of emotions and cognition.)
