We, humans, are a walking, talking contradiction.  The traits that we tend to hate in others are generally traits we, ourselves, hold.  That is not meant to be a concrete observation; however, there is some truth to that.  We will deny it, obviously, but that does not make it any less true.  Some of us hate people who drink alcohol but are the ones who pop a bunch of pills.  We want to have fun, but we slave away and don’t take vacations.  We tell people not to judge a book by its cover, but we think the guy with the tattoo will stab us in the kidney.  I could offer solutions, but I would just be contradicting myself and repeating the cycle.
