Half full or Half empty?

I often heard of this argument, do you look your glass as half full or half empty? Me? I dunno, maybe looking the glass half empty suit me more.

Explanation :

Those who see glass half full is the one expecting the glass to be full someday. Meaning to say, it might be people with vision, optimistic and aim for something big. On the other side, it can also denote as person without satisfaction, always hoping for more and a dreamer.

Those who see glass half empty is the one expecting the glass to be empty someday. Meaning to say, it might be people with optimization, opportunist and maximizing potential. On the other side, it can also denote as person without willingness to change, easy to satisfy and "dont-fix-something-not-broken".
