First of all it's not about studying hard it's about studying smart. The problem with most of the medical aspirants is that they aren't very well aware of the syllabus.

If you make yourself aware of the syllabus your work is half done. Believe it or not but the syllabus of the NEET is amongst the easiest of all ( when compared to exams like JEE ADVANCED etc..) . You just need to stick to the syllabus and focus on NCERT.

Most of the time, coaching classes and your bachmates use all the kinds of study material including a lot of books and notes. But believe me it's not the quantity of your knowledge that matters in the examination hall but the extent to which you have practiced the basics. So don't give a shit to what people around you are focusing on. Make a and focus on it.

Distractions are an obvious thing at our age, but you need to keep this in your mind that every distraction is temprory but the goal you have is the source to permanent joy.

One possible way is by asking yourself one simple question every time you do something “ How will this help me in achieving my goal?” If the answer is not satisfactory enough. Just let it go .

At last, I would say work not just for your own dreams but for your family's dreams. Give them something to be proud of.
