Frustrated conversations

At the beginning of the semester in my university, surely there are many conversations among students about courses which is the easiest and which is the hardest to study like many students do.
First, I have effected by their opinions about that, then I decided to let these conversations away from my mind to concentrate in each course I have to take. Actually, I have discovered that other’s opinions shouldn’t relate to us and we shouldn’t take by them because your failure could be related to these restricted opinions. So one must keep going without depending on others to make the best for himself.
