When I see someone, I analyze their look first, obviously. Now no one can really say they see personality first, because thats just ignorant. If you say an ant, you wouldn't see it's personality first.
After that I usually try to talk to them, and according to their response I know what kind of person they are. Then I probe a little deeper according to their personality type, and after I know what kind of person they are and the analyzing is complete.
I look at life as shoving out anything bad or dramatic, and keeping in thoughts of happiness. I remember the good times during the bad times, or I might (if it's bad enough) think of how it could be worse. So I'm very much of an optimistic person. Only one person has seen me in a bad mood when I think about it.
