Answer 2

Thats the same condition as mine. You should avoid all distraction. Always think about your goal in life which will motivate you to pay attention to your studies. Write your goal on a paper and stick it in your room so that you can see it everyday as you wake up. Stay healthy and be happy. Hope this helps you
