Teamwork is a strategic decision.
Smaller groups of people can establish trusting relationships.
Teamwork requires some sacrifice up front; people who work as a team have to put the collective needs of the group ahead of their individual interests.
Team synergy has an extraordinary impact on business results.
People who have a sense of peace that their priorities are in the right place also have a sense of humility and a realistic view on life.
For organizations seriously committed to making teamwork a cultural reality, I'm convinced that 'the right people' are the ones who have three virtues in common - humility, hunger, and people smarts.
