Yeah, life is like a hourglass. Everything end just like that, sometimes it ends without explanation.

We don't know why it's happened, why we have to suffer, why must we end to the bottom,

Alot of things must be in your head. Nothing can answer to your particular question.

I know, coz ive been through it and till now i still wonder why we live in this world,

but actually the answer is in our hands.

it's all depends on us. 

Depends on what u aiming in life.

Jiayou in life people!
