Specialization is a ­trade-­off: pursuing one course means not pursuing another. It’s narrowing your focus to increase your impact. In a world of infinite knowledge and finite time, specialization is the key to unlocking mastery. It’s about going deep, not wide. Specialization has risks. If the world changes, what was once a valuable specialty can become obsolete. And yet, we need specialists. You wouldn’t want a generalist doing your brain surgery or a root canal. Ultimately, specialization is about where you spend your time and effort. It’s how you stand out. It’s choosing to be great at one thing instead of okay at many.
