Practicality puts bounds on how much to rabbit hole.

A theoretician in the purest sense is removed from practical constraints and timelines. He can, in principle, keep pursuing a subject until the day he dies.

A practitioner is aiming for a practical result within a time frame. Because he has to deliver, he cannot afford to focus on developing a deep or exhaustive grasp of any particular thing. His focus isn't knowledge, after all, but the practical result. He will lean more on what he already knows, however limited, rather than pursuing new knowledge. He is less concerned with verifying the truth of claims himself and more concerned with trusting claims tactically by knowing whom to trust and when.

So, in the capacity of practitioner, you must learn prudence, which is the virtue of knowing what should be done in a given situation. It is the basis for the moral life, as morality concerns itself with right action and right decision making.

i really like that pov
