One thing I commonly hear in response to a question of the form “How can I effectively learn X?” Is “through experience” or “you just have to do it”. One frustrating thing about that response is that it takes skill to know what to focus on while practicing. In some domains like sports, people recognize that coaches are useful for learning what to focus on as you practice. It would be great if there were coaches for skills such as a software engineer’s prioritization, planning, and estimation of day-to-day tasks.
