In overgeneralization, an extrovert may agree group activities can provide with more important skills for life than working solo. In reality, an individual work can facilitate personal growth while there is only room for cooperative skills to learn in team efforts.
No matter where a person is, there is not so much to earn by playing a good mate. The best a great key player in an organized groups of people could experience would be how to work with many people. It is true that tasks may complete with minimum afforts. In sports, mainly in football, nobody can play alone to win a football match. In order to score in the game, it is necessary to pass the ball to the other footballer to have a goal. Similarly, in class presentations when paired with others, there is room to know how to study with peers. If one fail, all members of the assignment fail. Therefore, the most essential possible outcome by becoming a decent team member is learning to fit in the world and there is nothing more to it.
From my point of view, nobody wants an average person and everyone needs to strive to become the best. Hence, there is no need to learn how to behave in assigned tasks with others as in the end the overall score is based on how a person outperformed compared to those in the same task. To think logically, most of the time you are alone and it is survival of the fittest. Once you lose, you die in the battle you are fighting for. A student should aim for becoming top of the class. Similarly, the ultimate goal for an employee should be a general manager. Therefore, it is important not to waste time thinking how to earn a seat with others but rather think of becoming the number one.
To conclude, an individualist must aim for earning the number one spot in every cases. There are not many things to learn in group works.
