Also, study what interests you.
Rebbi said: A person can learn Torah [successfully] only from the area [i.e,. only within the topic] that his heart [currently] desires. For the verse says: [Psalms 1:2] ‘But his desire is in the Torah of Hashem.’
(The commentary adds that “According to Meiri, Rebbi speaks of where to begin [a session of] study.”)
