Here is a principle worth writing down: ideally, almost nothing in your work or study hours should be happening that is not moving you toward your actual goals. That sounds obvious. But watch how most people actually spend their time and you will see a very different story. There is a four-part approach to owning your hours properly. First, protect your schedule. Decide in advance what your most important work is, and block time for it before anything else fills the gaps. Second, stop treating things that look like work as if they are actually productive. Attending a meeting you contribute nothing to, checking messages every 15 minutes, reformatting a document nobody asked you to change — these feel like work because they take time and energy, but they do not move you forward. Third, remove tasks that are not a core competency for you. Ignore, minimise, or hand them to someone better placed to do them. Fourth, get better at the things that matter most. Skill at the right work is a multiplier. A neonatal doctor with two hours of meetings a day can save thousands of premature babies each year. A colleague with six hours of meetings and a packed inbox may save none. The issue is not effort. It is what the hours are actually being used for. Activity is not progress.
