When I was 17 or 18, I used to think that 21 was quite far away and nothing would change between now and then.

I now stand corrected. I feel that ever since I turned 20, all this noise in my head is growing louder and louder. It's not necessarily bad noise, just that I think more and more and more and more and more and more. It is as if my brain is trying to label everything, form an opinion, a perception, a concern about everything. A race.

And it has become more evident ever since I entered uni and learnt so many new concepts and new information about old things. And these few days, as I digest my interesting readings and lecture material for one of my modules. One of them says that signs are everywhere, and that "the more you know, the more you see". How very true. Knowledge is enlightening, it helps you see. But what if it also makes you myopic? By "seeing" so many things, your brain will have to choose something to focus on and you might choose to put out of focus some things that are really more important.

It's all mind-boggling, all these knowledge and opinions and perceptions. Shut up brain.
