A talmid chochom is not a job like being a sofer! By tefillin the Torah says you put on tefillin gomarnu ther’s nothing else no chiyuv to make them. However, by Torah there are requirements to know the entire Torah (veshinantom seyehu divrei Torah mechudadin al picho) and to sit and learn with all your kochos with glatt hashkofos obviously! There you go!
