a few thoughts that might help you inshaAllah. - study as early as possible when you are fresh, ideally in the morning after having a good sleep. - study before your meals, not after. - do not quit if you are stuck on something and cannot understand, just take a note of it and move on. ask teachers/ulama later. personally, it is the most difficult part for me, and sometimes it takes months to get a proper answer. - do not study just one subject for extended hours, when you feel you are getting bored then either switch to another subject or simply stop reading and do something else. - make use of the time that you pass in doing other things; for example, you can memorize the Quran, short ahadith, or short textbooks (mutoon) of Islamic sciences while you are doing a walk, driving your car, waiting for your appointment somewhere, etc. smartphones are very handy in this regard. - if you are not attending an Islamic school/madrasah where you must study 5 to 6 subjects every day then it is better that you focus on a couple of books at a time, finish them, then move on to other books. - spend more time on learning Arabic before diving into tafasir, hadith shuruh, fiqh and usul al fiqh books, it will save a lot of your time later. - my personal opinion - study for a year or two without targeting for exams; for example, enroll for exams of the first year of dars-e-nizami when you are studying year 3 books. - avoid social media and tv as much as you can.
