Reading is fun. Not to mention, reading an old book is more fun. At one time, you may have felt that you have understood the content. Unfortunately, it is not the case. A few days ago, I started to reread one of my old book. To my surprise only last night, I realized what I thought I have understood a few years back, turned out to be different.
I found that, I only understood chapter A to X and the other two chapters were difficult to be understood. It's like a mystery but I will keep reading until I understand. Maybe to understand the content well, I need some knowledge and to feel it, I need some experiences or maybe just a matter of time. Anyway, it's an interesting book.:))
