The Parking-Lot Sweeper
Both my parents came from towns in Mexico. I was born in E1 Paso, Texas, and when I was four, my family moved to a housing project in East Los Angeles.
Even though we struggled to make ends meet, my parents stressed to me and my four brothers and sisters how        we were to live in a great country with limitless opportunities. They       us with the ideas of family, faith and love.
I got my first       job when I was ten. My dad injured his back working in a cardboard-box factory and was retrained as a hairstylist. He        space in a little shopping center and gave his shop the flowery name of Mr. Ben’s Coiffure. The owner of the shopping center         my Dad’s payment for cleaning the parking lot three          a week, which         getting up at 3 a.m. Mom and I helped         dustbin and pick up rubbish by hand. It took two to three hours to clean the lot. I           sleep in the car on the way home.I did this for two years, but the lessons I learned have          a lifetime. I obtained discipline（自律）and the importance of work, and learned at a(n)         age the importance of balancing life’s competing interests——in my       , school, homework and a job. This        helped during my school years, when I worked 40 hours at a fast-food restaurant while taking a full         of college preparation courses.
The hard work        off. I attended the U.S. Military Academy and went on to         graduate degrees in law and business from Harvard.          , I joined a big Los Angeles law firm and was elected to the California state assembly（州议会）. In these jobs and in everything else I’ve done, I have         forgotten those nights in the parking lot. The experience taught me that there is value in all work and that if people are working to       for themselves and their families, that is         we should honor.
