I grew up in a tiny Baltimore row house in a faraway mountain area. My parents        the necessities of life        they couldn’t give much more. If I asked my father        a pair of jeans, he would say, “If you want them, make the money and buy them       .” He wasn’t being mean; he just couldn’t        them. From age 12 on, I did part-time jobs after school.
When I         from high school, I joined the navy. Soon I was in a boot camp(新兵训练营) at Parris Island, S. C., where I learned that life in the navy centered around completing daily     . 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         to graduate from the U.S. Naval Academy 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.       I was being asked to give encouraging        to business groups, educators and kids across the country.
But I consider the boot camp my first real       , and my life is still guided by the      lessons I learned there. It taught me discipline, friendship and the pride related to setting a task every day and working hard to        it.
