When I was preparing for UPSC, I liked reading a lot. And this entire section of the bookshelf is essentially books that I had read during my preparation. It's very useless. You don't have to read so many books. And naturally, the closer I got to the exam, I realized that I won't be able to remember all these books. So I thought, what should I do with the notes? And because I was lazy, I thought I should take the best notes ever, if I get them somewhere. And that, again, led to problems. Eventually, I realized that I have to make my own notes, which I did in this format. You'll see that it's written in very small writing. But eventually, these notes are of no use. These can be the best notes ever, but if I don't read them again, they are useless. So that's what you have to realize with your own notes also. They may be the best notes that you'll ever find, but if you don't read them again, they're useless. So read your notes.
