Expectations

 Reality happens and often we don't have any control over it.  But we do have control over our expectations.  You are waiting for a subway to come.  Your expectation is that it will arrive in a few minutes.  The reality is that the subway broke down and is clogging up the tunnel.  You go into a fit.  You are unpleasant to another person who had nothing to do with the breakdown.  You leave the station, go to a bar and get drunk as your answer to the broken subway.  Maybe you call home and yell at whoever answers the phone.  Someone besides you must suffer this subway breakdown.  Now you are having a breakdown.  All because you could not let go of your expectation.  Expectations get in the way of happiness and sanity.
