I'm not good guy

Normally, guys should KNOW what?
know how to comfort ppl,
know how to make a girl happy,
know how to take care of others,
know how to talk well,
know how to use their brave,
and more and more...

BUT i think i am not a good guy...
i dunno how to comfort ppl,
when ppl sad, i can do is just accompany,
not even speak some thing to them...
i dunno talk as well as other,
cant get a good communication with others...
my knowledge was less,
dunno this, dunno that,
so i cant join ppl topic when chatting...
but sometimes i am not interested in that...
and actually, every time what i talk is just rubbish..
non-sense...
so i choose to listen...
better let me know more then only i talk...
what kind of guys is this?
a useless guys...
no more word can instead...
I even not enough courage to chase what i wan...
lack of confidence...

Can i make a change?
i know i can, but it is hard...
ppl said, time can make every things change...
but do u know how long it take?
I am trying my hard to be more confidence since last few years...
but, still not enough...
haiz~what kind of guy is this?
i think should be called as a useless guy...
no more word can instead...

ARGHHHH~
