We all live a life, some are happy with it.. coz they know how to be happy, loving themselves and few may be not. the reason may not be the sole one, its jus bcoz they fail to love themselves :)
If u want to be happy, then learn to love yourself.
then all you find is happiness. 
I KILLED A COCKROACH (lol)
It was suffering. Neither it was
able to turn itself right, nor could give up the life. Maybe it was begging for
the help for getting to be turned over. I could clearly see that its legs were
broken… Few minutes more and it was dead! If it will be turned over, it would
live its life struggling.., else it had to let its life end just like that.I am talking about nothing else, but
a cockroach. I guess, the creature was into that situation for more than a
minute.I went nearer to it, took a deep breath, and killed it with all my force I could put on the racket.
I am not cruel though, I did feel pity for the insect. At the same time I felt totally bad and sorry for it. Even if I would turn it right, it would be dead one day and I am pretty sure, it would not get an easy death. Who knows! It might be separated into two halves or been stepped by someone, or grabbed by a frog maybe!So, I killed a cockroach… just because I didn't want it to live a life struggling…without pair of legs and helpless….
