There are many things that we can and should do by ourselves. But, much of today's chores are best done by groups of people. In sports, a fully cooperative team with talented players often leads to a winning combination. In business a group of associates that are cooperatively working toward a shared goal often leads to winning.

Organizations of all kinds are looking for people who can turn their average groups into winning groups. Your contributions in this area will aid you in getting the job, and maintaining it.
