Stop being so nice all the time.  It makes people want to puke; enough already!  Like eating too much candy at one time, it just doesn’t sit well on the stomach.  There is a difference in being nice and being kind.  Clear is kind. Accountability is kind.  Consistency is kind.  Discipline is kind.  Too many people confuse niceness with kindness.  There is a vast difference between being kind to someone and the fakeness of being nice all the time.
