Is the glass half full ?

Am I am optimist, pessimist or someone in between ?
I cant answer that honestly. I know too much about me, I think, or do I ? Well, if I cant answer this then who can ? And why do I want to know in the first place anyways?
Is there a better type, that is say If I turn out to be a pessimist, should I work on my attitude and reactions to become an optimist ? Anyways, there is a always a possibility that whatever folks perceive of me, thats not what I really am.
Whatever it might be, dont you guys think, it would be quite interesting to know that ! Or to find if my perception has changed over the years in my friends minds.
At the end of the day, who gives a bollocks anyways !
I am what I am :)
