Since I have been law pratitioner, the obstacle which I often came across while my research work was vague judgments which often overlaps and create cofusion that which case laws supports my case facts. In law practise it was very important that one should refer case laws which properly supports your case facts to make your case more strong before Hon'ble Judges.

Choosing the Right Topic: it was my problem in studying Msc degree in meteorology and I solved when I choose the right supervisor that made me complete my research perfectly and accurate.

As a field of humanities, film studies is a discipline mainly  based on subjectivity. In my written work, I have been always trying to operate/research within the biggest intersection of readers possible to prove my positions. This  attitude,  I think,  made it in a way harder to find the appropriate literature and texts needed for my research.
