World, Life, and People

I always wondered what is life all about, what is the meaning of existence and whats is world really. I tried to learn people, society. But at some point nothing really has a meaning. And things are totally crazy around. Everything appears the same, it may be a scribble or a sonnet, Sunset and the sunrise, everything seems to be exactly the same. Life is kind of hard all around when you care too much about it, but i figured out that its hard even if you don't care about it. All we hear about is the history of man kind, the history of people come and go, birth and death, culture change, civilization change. But still we are not stable in our way of life. I couldn't figure out any decision about the world, or people, or the life. If you have a clear vision about any of the above, just comment and let me know about it.
