     When I was nine years old I lived in a small town. I found an ad for selling greeting cards in the back

of a children's magazine. I thought to myself I could do this. I begged my mother to let me send for the

kit (配件). Two weeks later the kit arrived. The next three hours later, I returned home with no card and

a pocket full of money shouting, "Mama, all the people couldn't wait to buy my cards!" A salesperson

was born.

When I was twelve years old, my father took me to see Zig Ziegler. I remember sitting in the dark hall

listening to Mr. Ziegler raise everyone's spirits up to ceiling. I left there feeling like I could do anything.

When we got to the car, I turned to my father and said, "Dad, I want to make people feel like that." My

father asked me what I meant. "I want to be a motivational speaker just like Mr. Ziegler," I replied. A

dream was born.

     Recently, I began pursuing my dream of motivating others. I realized that everything I had

accomplished - the graduate degree, the successful sales career, speaking appointments, training and

managing for a major fortune 100 company as a senior manager- had prepared me for this moment. I

told my boss who was a great leader I would leave the company though I might not reach such a height

in career. He told me to proceed and he believed I would succeed.

     Having made that decision, I was immediately tested. One week after I gave notice, my husband was

laid off from his job. We had recently bought a new home and needed both incomes to make the monthly mortgage (抵押) payment and now we were done to no income. I even planned to turn back to my

former company, knowing they wanted me to stay but I was certain that if I went back, I would never

leave. I decided I still wanted to move forward rather than end up with a mouth full of "if onlys" later on.

A motivational speaker was born.

     When I held fast to my dream, even during the tough times, the miracles(奇迹) really began to happen. In a short time period my husband found a better job. We didn't miss a mortgage payment. And I was

able to book several speaking appointments with new clients (客户). I discovered the incredible power

of dreams. I loved my old job, my workmates and the company I left, but it was time to get on with my

dream. To celebrate my success I had a local artist paint my new office as a garden. At the top of one

wall she marked, "The world always makes way for the dreamer."
