Team is very necessary is every work in life. Without team work nobody success in life.when a man work in a team his work sprit is increase very fast and he can his work very properly but when a man do something alone he does not can that work properly.For this reason we should every work by teambase.when we work by team then every work we can successful and we should reached our aim. 
The truth is that teamwork is at the heart of great achievement.
