These could be anything from cleaning the camp to conducting mock(模拟的) battles. Completing these tasks successfully ______ discipline, team-work and responsibility. It didn’t ______ whether you were black, white or Asian; everyone worked together for the ______ of the company. I went on to graduate from the U.S. Naval Academic and later became an officer in the navy. The part of my job I ______ most was the consulting(咨询) meetings I ______ with the family members of the men and women in my ______, trying to help them deal with the long periods of ______. These proved popular and word of them spread. Before long I was being asked to give encouraging ______ to business groups, educators and kids across the country.
