Let's suppose hypothetically I am subject A for extended periods of time and devoting my all my time to it. At some point, I feel I hit a plateu , similar to trying to drive in mud, I feel stuck without being able to progress further.
What would be the best move to overcome this stuck feeling? I see three possible options of proceeding:
I drop the subject I am doing and try something else for a few days time
Continue trying to bash through exercises on the subject
I drop the subject for a few hours and return
I have repeatedly tried (2) and (3) with not much success. I am starting to think (1) maybe the best way , has there been any research on how to over come learning difficulties when the student comes at a mental block in self studying?
