A Yeshiva student should not be searching for questions or trying to come up with novel ideas.

If they come up naturally, that's fine, but the main focus should be diligent engagement in studying Nigleh and Chasidus. This also applies to your concerns about Mussar and your path in the service of Hashem. I’d like to remind you again to make sure you’re doing Chitas. https://www.torahrecordings.com/rebbe/igroskodesh/011/012/3787
