The article argues that software engineers should aim to work at 80% utilization, leaving 20% of their time free to handle high-impact tasks and avoid burnout. This approach allows engineers to be more productive and have a greater impact, as they can focus on the most important tasks and avoid getting bogged down in low-priority work. The author suggests that doing nothing can be beneficial, as it allows engineers to rest and come back to problems with a fresh perspective. By working at a slower pace, engineers can also avoid making silly mistakes and be more effective in the long run.
