A

My parents influenced us with the concepts of family, faith and patriotism when l was  young．Even though we struggled to make ends meet, they stressed how fortunate we were to - live in a great country with limitless opporturuties．

I got my first real job when l was ten． My dad, Benjamin, injured his back working in a  cardboard - box factory and was retrained as a hairstylist． He rented space in a little mall and gave his shop the fancy name of Mr． Ben's Coiffure．

The owner of the shopping center gave Dad a discount on his rent for cleaning the parking． lot three nights a week, which meant getting up at 3 a．m．To pick up trash,  Dad used a little machine that looked like a lawn mower． Mom and I emptied garbage cans and picked up litterby hand．It took two to three hours to clean the lot． I'd  s1eep in the car on-the way home．I did this for two years, but the lessons I leacmed have lasted a lifetime,I acquired' disci-pline and a strong work morality, and leamed at an early age the impmtance of balancing life's competing interests-----in my case, school, homework and a job．This really'helped during my senior year of high school, when l worked 40 hours  a  week flipping hamburgers,at a fast – food  joint while taking afull load of college - prep courses．  The hard work paid off ．I attended the U．S．Milttary Academy and went on to reaceive graduate degree  in law and business from Harvard． Later,I joined a big Los Angetes law firm and was elected to the California state assembly． In these jobs and in everything else I’ve  done,I have never forgotten those nights in the parking lot．The experience taught me that there is dignitty in all work and that if people are workmg to provide for thems elves ahd their families ,that is something we should honor．
