Who am I?

I do not understand myself. I don't know where I come from, where I'd go, or what I want. Perhaps the easiest question is the last one. I like theories, love reading books and getting exposure to new, exiting ideas. I value ideas more than fact. I love things that are beautiful, be it visually, musically, or theoretically. I cannot understand people's obsession with new bags and shoes (if they look normal and such--don't quite get fashion, how can something so normal or ugly be worth so much). I cannot understand idol-ism. I cannot understand why people will hold on to a belief so dearly even if they know it may be wrong.

I realised that I'm actually quite confused about how things work in the environment around me. Normally I'm not interested, but once I start to delve into how people think, why would they do this and that, I get headaches.

Here, I'm going to make a list of things I cannot understand:

1. Politics
2. Economy
3. Fans--idol-ism
4. Love for branded goods
5. Meaningless chats about how stuff like manicure, shoes and stuff
6. People eating insects
7. Why mediacorp can't find good shows to put on its channels
8. Why would people watch something they do not like to watch just to "kill time"
9. Why would people choose to be ignorant when they are given the chance to be not to

The list is just a start. I think there are a lot more of things which I don't understand but I can't think of any in the present moment. I feel that the way each person perceive the world, his thinking, logic and feelings are very different from others. Just as mentioned by the vsauce video:

There are no ways to tell what is going through the mind of another person. There are no ways to tell a lot of things, such as whether the society's code of conduct is right, whether humans are meant to be connected biologically (ie there are some similarities between the thinking of two humans). Inside each of us, our perceptions of the outside world are only limited to us. We are very much alone.

I also understand that there will be some things we will never know, some things we will never make sense of because they aren't meant to make sense, and some things we will never understand.

Am I the only one being bugged by this uncertainty? I just find the thought that I'll never able to fully understand even myself be quite frightening.
