Whether you're a student working on a group assignment, an employee managing a large project or an athlete, you will have to rely on someone else. Unfortunately, you don't always get to choose the people you work with. Circumstances and decisions beyond your control will throw you together with people of all walks of life.
To achieve the shared end result, you have to rely on the people you're teamed up with. However, just working on or believing in the same goal doesn't make you a team. Working on building trust and believing in one another to do your part is what makes a real team.
Teamwork makes the dream work, but the team works best when mutual trust and respect are involved.
