One of the great things about a mule is that they can carry a great deal of weight. If you put a small load on its back it will happily bounce down the trail. If you place a medium size load on its back it will carry the load without complaining. If you place a large load on its back it will complain but still successfully maneuver the load. However, if you overload the mule it will stop moving completely.
This is a lot like workloads at the office.
and the work ethic they instilled in me. Why can't I be more of a slacker?
