How to Infect a Group With Productive Emotions

People are naturally more emotional and permeable to the moods of others. Work with human nature and turn this into a positive by infecting the group with the proper set of emotions. When asking for help, appeal to people's self-interest, never to their mercy or gratitude. Change up routines, surprise the group with something new or challenging. This will wake them up and stir them out of complacency that can settle into any group that achieves success.
