Cate Hall's list includes a thought-provoking suggestion: ask yourself if there's a better way to do tasks throughout the day. The author reflects on this idea and questions whether creating an app for it is necessary, given that computers excel at such tasks. However, he decides to create the app himself, framing it as something he can "just do." The process unfolds quickly. With only 90 seconds left on his train ride, he describes the app to Claude, an AI, which then builds it for him. The app is designed to send notifications every 100 minutes, randomly reminding him to consider if he can improve on what he's currently doing. After the train ride, he spends about five minutes reviewing the code and installing it on his phone. He adds a feature and some monitoring functionality, completing the project in less than 15 minutes of total time. The takeaway emphasizes a hands-on approach to problem-solving and leveraging available technology. By breaking down the task into manageable steps, the author demonstrates that even a seemingly complex project can be tackled efficiently. The app is now functional on his phone, reinforcing the idea that taking action is often more feasible than it seems.
