What I hate:

People who spend every waking moment complaining about their misfortunes and making mountains out of molehills. To them, I say: no one ever said life was easy; life does not have to be perfect; be grateful for what you have and, more importantly, for whom you have; stop complaining about things you have no control over; stop wishing that things you cannot control were different and last but not least, GET THE HELL AWAY FROM ME!... Pessimism is contagious, and I am sick and tired of your dark cloud hovering over me. 

Take a chill pill and go pollute someone else's soul!

(and while you're at it, take your head out of the sand: you're not being a realist...you're being a jerk!)

 

A pessimist sees the difficulty in every opportunity.
An optimist sees the opportunity in every difficulty.
―Winston Churchill
