Hogwarts : I can see your face

Wade: I only have seven years to study at Hogwarts, which means there are only 266 weeks excluding holidays! Even if I can finish a book in a week, 266 weeks is only 266 books! How many magic books are there in the Hogwarts library? Thousands of them!
Time is running out, how can I not seize the time to study? ! I will never allow anyone to destroy my learning environment - not even the Dark Lord!
No, no, no, I don't just love knowledge.
I'm just greedy.
