all human have "4" SELF

all of us have 4 self..
-open self
-blind self
-unknow self
-hidden self

all of us can see our open self clearly...
i am a girl,
i am a chinese...
this open self of us can been seen clearly by only looking at our apperance.

our friend can our blind self easily,
but when we want to see our blind self,
this may have some difficulties for ourself...

all of us also have also unknow self
unknow self is something that maybe youself know but others do not know,
another situation is other know but yourself don't know...
this is like you have secret that you don't want let people know..

lastly,
all of us must have hidden self...
like hidden talent...
this hidden talent might need times to be cultivate
eg:creative talent, singing talent...
