Individual excellence in performance and team work

There was once a man who had three sons. Much to fathers chagrin the boys shared little in common. 
One day he asked them "bring me as many branches as you can carry". 
The boys ran into the woods to gather branches and each came back with a bunch of branches. He said "take any one branch now and try to break it". That is easy the boys said and they broke their sticks in half. "Now bind all of them with a rope together and try to break them again" 
They tried but the branches, that so easily could be broken separately, bound together were as strong as steel. "You see" their father said, "what you do with these poles can also happen to us. If you only look at yourself, you are vulnerable and you stand alone. Together we are strong and what applies to the poles, also applies to us".
