I Hate Me

what is the definition of life ?

to succeed in everything...

to pursue everything you want...

or    be happy for whole life....

I think the happiness is more important than anything

but 

it is not true with reality

there are many unhappy thing in our life and we can't avoid that

we just can accept that, because we have no choice

now

I select one way, but I can't walk continually untill it is over

I really hate myself and I can't do that thing completely

why????

how can I do......
