How do group behaviors impact motivation?

Motivation of a group have a serious impact on individual behavior. the fears or joys of a local group may be spread to the masses. For example, a rock concert takes place in a confined space, a building or an open area. The people watching the concert from their seats are the crowd and they exhibit crowd behavior, hence motivating people in groups/masses. When an act/activity like mentioned in the example above is performed, the impact is certainly more because the act is believed to be fun or true or powerful because it was performed by a group of people rather just one. The team work is seen.

Group behaviors do have an impact when it comes to motivating someone. There is a possibility that a person doesn't get motivated by an single individual no matter how much he has tried to listen to him or follow him. May be self motivation might not work on a person or it may not last for a longer time. There has to be someone else or more than one person who are after you to push you towards your goals and guide you wherever required.
